A conviction does not always end the legal process, but the opportunity to challenge it is often governed by strict deadlines. Time limits for filing post-conviction motions vary by jurisdiction, the type of claim, and the remedy sought, making the starting date especially important.
Federal and state rules may set different filing periods, and certain events—such as properly filed state proceedings or newly discovered evidence—can affect how time is calculated. Missing a deadline may prevent a court from considering a claim, so careful verification is essential.
When the Filing Clock Starts After a Conviction
The filing clock does not always start on the date a judge announces a conviction or imposes a sentence. The controlling date depends on the type of post-conviction motion, the court involved, and the applicable federal or state statute.
For federal habeas petitions under 28 U.S.C. § 2254, the one-year period generally begins when the conviction becomes final after direct review concludes or the time to seek that review expires. Under 28 U.S.C. § 2255, the period usually begins when the judgment becomes final, though the statute provides alternative start dates for certain claims.
A direct appeal can therefore affect when the deadline begins. If no appeal is filed, the time allowed to appeal typically must expire first; if an appeal is decided, further review may affect finality. The precise calculation depends on the case’s procedural history and applicable rules.
State deadlines may use different triggering events and calculation rules. Because time limits for filing post-conviction motions vary by remedy and jurisdiction, identify the specific motion and governing law before calculating a deadline.
Federal Deadlines for Post-Conviction Motions
Federal deadlines for post-conviction motions depend on the statute used and the date from which its limitation period runs. Under 28 U.S.C. § 2255, a federal prisoner generally has one year to seek relief from a federal conviction or sentence. Under 28 U.S.C. § 2254, a person in state custody generally has one year to file a federal habeas petition.
The one-year period usually begins when the judgment becomes final, but the statutes provide alternative starting dates in certain circumstances, such as when an unconstitutional government-created impediment is removed or a newly recognized constitutional right applies retroactively. The applicable trigger depends on the claim and the case’s procedural history.
For § 2254 petitions, time during a properly filed state post-conviction or other collateral review proceeding generally does not count toward the federal one-year limit. This tolling does not restart a period that has already expired, and a state filing made after the federal deadline cannot revive it.
- Section 2255: generally applies to federal convictions.
- Section 2254: generally applies to state convictions.
- Both: require careful calculation of the starting date and any applicable tolling.
The one-year limitation period under 28 U.S.C. § 2255
Under 28 U.S.C. § 2255(f), a federal prisoner generally has one year to file a motion to vacate, set aside, or correct a sentence. The limitation period runs from the latest of four statutory dates, not necessarily the date the sentence was imposed.
The most common starting point is when the judgment of conviction becomes final. If the prisoner did not appeal, finality generally occurs when the time to file a direct appeal expires. If an appeal was filed, the date depends on how the appeal concluded and whether further review was sought.
The year may instead begin when an unconstitutional government-created impediment to filing is removed, when the Supreme Court newly recognizes a right made retroactive to cases on collateral review, or when supporting facts could have been discovered through due diligence. These alternatives have specific legal requirements.
Because the time limits for filing post-conviction motions can turn on precise dates and procedural history, prisoners should verify the applicable trigger and deadline. A § 2255 motion filed after the period expires may be dismissed unless a legally recognized basis for relief from the deadline applies.
The one-year limitation period under 28 U.S.C. § 2254
For most state prisoners seeking federal habeas relief under 28 U.S.C. § 2254, the Antiterrorism and Effective Death Penalty Act sets a one-year limitation period. The deadline generally runs from the date the state judgment becomes final after direct review concludes or the time to seek that review expires.
The statute provides alternative start dates in certain circumstances, including when an unconstitutional state-created impediment is removed, when the Supreme Court initially recognizes a newly applicable right, or when the factual basis of a claim could have been discovered through due diligence. Which date applies depends on the claim and the case’s procedural history.
The year is generally paused while a properly filed state post-conviction application or other qualifying collateral review is pending. It does not usually restart the one-year period; any time that elapsed before the state filing may still count. A late or improperly filed state application may not pause the federal clock.
Because calculating these time limits for filing post-conviction motions can be complex, petitioners should verify the finality date, applicable statutory start date, and effect of each state filing. The one-year deadline is subject to limited exceptions, and missing it may bar federal review.
Counting time during state post-conviction proceedings
Under the federal habeas statute, a properly filed state post-conviction application generally pauses the one-year deadline under 28 U.S.C. § 2254. The time that elapsed before the state application was filed still counts, so filing in state court does not restart the clock.
The pause usually continues while the application is pending through the state’s review process, including any timely appeal. It ends when state post-conviction review concludes; a later request to reopen the case may not extend tolling.
An application must be “properly filed,” meaning it satisfies applicable state rules governing matters such as filing requirements and deadlines. A state petition filed after the state deadline generally does not toll the federal period.
Time spent seeking review in the U.S. Supreme Court after state post-conviction proceedings end generally does not count as time the application remains pending for statutory tolling. Because the rules can turn on procedural details, calculate the remaining time carefully when assessing time limits for filing post-conviction motions.
State Post-Conviction Filing Deadlines
State post-conviction filing deadlines vary by jurisdiction and may depend on the type of claim, the court, and the remedy sought. Many states impose a fixed period after conviction or sentencing, while others set deadlines tied to events such as the completion of direct appeals.
The time limit may also differ for claims based on newly discovered evidence or changes in constitutional law. Some states allow exceptions to ordinary deadlines, but the requirements can be narrow and may demand specific supporting evidence.
A state’s rules may require filing in the trial court, an appellate court, or another designated forum. Missing a deadline can result in dismissal, although available exceptions and procedures vary. The rules governing time limits for filing post-conviction motions should therefore be checked in the relevant state’s statutes and court rules.
Because deadlines and exceptions can change, verify the current law and calculate the filing period from the event specified by the applicable rule. A conviction’s appeal history may affect that calculation, so the relevant docket and procedural record should also be reviewed.
Deadlines for Motions to Correct or Reduce a Sentence
Deadlines depend on the type of sentence-correction motion and the court involved. In federal criminal cases, a motion under Federal Rule of Criminal Procedure 35(a) to correct a sentence resulting from an arithmetical, technical, or other clear error must generally be filed within 14 days after sentencing.
Rule 35(b) permits a federal court to reduce a sentence for substantial assistance to the government, but the motion must be made by the government—not the defendant—and is generally subject to a one-year deadline after sentencing. Limited exceptions apply when the defendant’s assistance or information becomes useful later.
A motion under 18 U.S.C. § 3582(c)(1)(A), often called a compassionate-release motion, has no fixed filing deadline. A defendant generally must first request relief from the Bureau of Prisons and either exhaust administrative appeals or wait 30 days. State rules differ, so check the governing statute and court rules; these deadlines are distinct from broader time limits for filing post-conviction motions.
Newly Discovered Evidence and Time to File
New evidence may provide a separate starting point for a federal post-conviction deadline, but the rules differ by proceeding. Under 28 U.S.C. § 2255(f)(4), a federal prisoner generally has one year from when the facts supporting the claim could have been discovered through due diligence. Under § 2244(d)(1)(D), a state prisoner’s one-year federal habeas period may begin when the factual basis of the claim could have been discovered with due diligence.
The evidence must concern facts supporting the claim, not merely offer a new legal argument or a different interpretation of known facts. The date of actual discovery may not control if reasonable diligence would have uncovered the facts earlier. Whether diligence was sufficient depends on the circumstances.
For a newly discovered-evidence claim, consider:
- What the evidence establishes and when it became discoverable;
- What reasonable steps were taken to locate it; and
- Which deadline and filing rules apply to the case.
State-law deadlines may use different standards or time limits. Because the time limits for filing post-conviction motions vary by jurisdiction and claim, verify the governing statute and court rules promptly.
Claims Based on New Constitutional Rules
A new constitutional rule may affect the deadline for a federal habeas petition, but only in limited circumstances. Under 28 U.S.C. § 2244(d)(1)(C), the one-year period for a state prisoner’s § 2254 petition may begin when the Supreme Court initially recognizes the right, if that right has been made retroactively applicable to cases on collateral review.
For federal prisoners filing under 28 U.S.C. § 2255, a similar provision starts the one-year period when the Supreme Court initially recognizes a newly established right and makes it retroactively applicable on collateral review. A ruling that is merely new or favorable does not automatically qualify.
Retroactivity is a legal determination, and the Supreme Court’s decision must satisfy the applicable standard. The deadline may also depend on other statutory start dates or tolling rules, so the date of the ruling alone may not determine the filing period.
Because these rules are narrow and fact-specific, anyone relying on a new constitutional rule should verify its retroactive status and calculate the applicable deadline promptly. Missing the time limits for filing post-conviction motions can prevent a court from considering the claim.
Tolling and Pauses in the Filing Period
In federal habeas cases, tolling can pause the one-year limitation period, but only under specific rules. The time limits for filing post-conviction motions may depend on the type of claim and the proceedings involved.
Under 28 U.S.C. § 2244(d)(2), the limitation period for a state prisoner’s federal habeas petition is tolled while a properly filed state post-conviction application is pending. The application must meet the state’s filing requirements, and a proceeding generally remains pending through the state appellate process.
Equitable tolling may apply in federal habeas cases when a petitioner shows diligent efforts to pursue their rights and an extraordinary circumstance prevented timely filing. It is assessed case by case and is not automatic.
Events that generally do not pause the federal deadline include:
- A petition that was not properly filed under state law.
- The time between the conclusion of state review and filing in federal court.
- Simply seeking legal assistance or being unaware of the deadline.
Rules vary by claim and jurisdiction, so deadline calculations should be verified carefully.
Statutory tolling during properly filed state proceedings
Under 28 U.S.C. § 2244(d)(2), the one-year federal habeas deadline for a state prisoner is paused while a properly filed application for state post-conviction or other collateral review is pending. The time already used before the state application is filed still counts.
An application is generally “properly filed” when it meets the state’s rules for filing, including applicable requirements for form, place, and timing. A state court’s decision that an application was untimely may mean it does not qualify for statutory tolling.
The application remains pending through the state review process, including appeals properly pursued within that process. The clock generally resumes when state collateral review ends; time spent seeking further review in the U.S. Supreme Court does not extend this statutory pause.
Because state procedures and filing dates can affect the calculation, people assessing time limits for filing post-conviction motions should verify the relevant state rules and docket dates. Statutory tolling does not restart the one-year period or excuse a filing made after it has expired.
Equitable tolling in federal habeas cases
Equitable tolling may pause the federal one-year deadline for a habeas petition under 28 U.S.C. § 2254 or § 2255, but courts apply it narrowly. A petitioner generally must show both that they diligently pursued their rights and that an extraordinary circumstance prevented timely filing.
The inquiry is case-specific. Serious attorney misconduct, for example, may qualify in some circumstances, while ordinary negligence or a lack of legal knowledge generally does not. The petitioner must also connect the claimed obstacle to the delay.
Equitable tolling does not automatically extend the time limits for filing post-conviction motions. A petitioner should document the circumstances, explain the steps taken to pursue relief, and show when the obstacle began and ended. Courts assess these facts under the governing law and relevant precedent.
Events that generally do not pause a deadline
Ordinary delays in a criminal case generally do not stop a post-conviction filing period. Waiting for a transcript, court records, or legal assistance usually does not automatically toll a federal deadline. A person should not assume that a request for documents extends the time to file.
A direct appeal does not ordinarily pause the federal one-year period while it is pending; the period generally begins when the conviction becomes final after direct review. Once the limitation period has started, routine court delays or an attorney’s workload generally do not suspend it.
Other circumstances, such as incarceration, limited legal knowledge, or difficulty accessing a law library, typically do not establish equitable tolling by themselves. Courts assess tolling claims under specific legal standards, and the result depends on the facts and governing law.
Because the time limits for filing post-conviction motions vary by remedy and jurisdiction, litigants should verify the applicable deadline rather than rely on an event to pause it. A late filing may be dismissed unless a recognized exception applies.
Successive Post-Conviction Petitions
A second or successive federal habeas petition generally requires advance authorization from the appropriate court of appeals. Under 28 U.S.C. §§ 2244(b) and 2255(h), authorization is limited to claims based on qualifying newly discovered evidence or a new, retroactive constitutional rule. A court may dismiss an unauthorized petition.
State rules also restrict repeat applications, but the limits vary by jurisdiction. Some states require new evidence or another recognized exception, and may impose separate filing periods or procedural requirements. The deadline for an initial application does not necessarily determine whether a later one is permitted.
Before filing another petition, check:
- Whether the court of appeals must authorize it
- Whether the proposed claim meets the applicable statutory criteria
- Whether state law bars or limits a successive application
These restrictions are distinct from ordinary time limits for filing post-conviction motions. A new petition may face both successive-petition rules and a separate limitation period, so satisfying one does not automatically satisfy the other.
Federal authorization requirements for second or successive petitions
Under the Antiterrorism and Effective Death Penalty Act, a federal prisoner generally must obtain authorization from the appropriate court of appeals before filing a second or successive motion under 28 U.S.C. § 2255. A state prisoner faces a similar requirement before filing a second or successive habeas petition under 28 U.S.C. § 2254.
The applicant must seek authorization from a three-judge panel of the court of appeals. The panel may permit the filing only if the proposed claim meets statutory criteria:
- The claim relies on newly discovered evidence that, if proven, would establish by clear and convincing evidence that no reasonable factfinder would have found the applicant guilty.
- The claim relies on a new rule of constitutional law, made retroactive to cases on collateral review by the Supreme Court, that was previously unavailable.
A district court generally cannot consider a covered successive filing without appellate authorization. Because courts distinguish successive petitions from certain later filings, and the rules can depend on the case’s procedural history, these time limits and authorization requirements should be verified before filing.
State restrictions on successive applications
State law determines whether a person may file another post-conviction application after an earlier one. Many states limit successive petitions, requiring claims to be raised in the first available proceeding. A later application may be dismissed if it repeats a claim already decided or presents a claim that could have been raised earlier.
Exceptions vary by jurisdiction. Some states permit a successive application when the claim relies on newly discovered evidence, a retroactive change in law, or facts showing actual innocence. These exceptions may have their own filing deadlines and strict proof requirements.
A state court may also require permission to file again or apply specific procedural rules before considering the merits. These state restrictions are separate from federal authorization requirements, and meeting one system’s rules does not necessarily satisfy the other’s.
Because state rules differ, check the applicable statute and court decisions promptly. The time limits for filing post-conviction motions can interact with successive-application bars, so delaying while assessing eligibility may jeopardize a potential claim.
Why a new petition may face separate procedural limits
A later filing may be treated as a new or successive petition rather than a continuation of the original case. That distinction matters because the rules for successive applications can impose limits separate from the original deadline for filing post-conviction motions.
In federal habeas cases, a prisoner generally must obtain authorization from the court of appeals before filing a second or successive application. Authorization is limited to specified grounds, such as qualifying newly discovered evidence or a new constitutional rule made retroactive by the Supreme Court. Without it, the district court generally cannot consider the application.
A new filing may also face a separate limitations analysis. For example, a later-discovered claim may have its own start date under applicable federal law, but that does not automatically make the petition permissible as successive. State procedures may impose separate restrictions as well, and the rules vary by jurisdiction and case type.
Because courts may classify filings by their substance rather than their title, reasserting or revising claims can trigger procedural barriers. The governing statute, prior filings, and court orders should be reviewed before submitting another petition.
Consequences of Missing a Post-Conviction Deadline
Missing a deadline may allow the court to dismiss a post-conviction motion without considering whether the underlying claim has merit. In federal habeas cases, the one-year limitation period is generally treated as a procedural bar, subject to applicable exceptions and tolling rules.
A missed deadline can also restrict later attempts to raise the same claims. Depending on the court and the type of proceeding, a later filing may be treated as successive, require prior authorization, or be barred under state procedural rules.
The effect is not always automatic or identical across cases. Courts may consider issues such as equitable tolling, newly available evidence, or a qualifying new constitutional rule, but these exceptions have specific legal requirements and are not guaranteed.
A deadline ruling may leave a person with limited options, particularly if an appeal or another remedy has its own filing period. Because the consequences depend on the governing statute, court rules, and case history, the applicable limits should be verified promptly.
Calculating and Verifying the Filing Deadline
Start by identifying the specific remedy and governing rule, since filing periods differ for federal habeas petitions, state post-conviction applications, and sentence-related motions. Confirm the relevant judgment date and any later event that may trigger a separate deadline, such as finality after direct review or discovery of new evidence.
Count calendar days under the applicable statute and court rules, checking how they treat the triggering day, weekends, holidays, and the filing date. Do not assume that mailing a document extends the deadline; applicable prison-mailbox rules and proof-of-mailing requirements vary.
Create a written timeline that records each potentially relevant date and any period that may be excluded or tolled. For federal habeas claims, verify whether a properly filed state proceeding affects the calculation, and assess any claimed equitable tolling separately.
Check the current statute, local court rules, and controlling decisions, because interpretations can change. When dates or procedural rules are uncertain, seek advice from a qualified post-conviction attorney promptly; waiting for certainty may leave too little time to file.
Protecting the Right to Seek Post-Conviction Relief
Protecting the right to seek post-conviction relief begins with identifying the correct deadline for the specific claim, court, and jurisdiction. Record the triggering event and filing date, then verify the calculation against current statutes, court rules, and applicable decisions.
Keep copies of judgments, appeal records, transcripts, and documents supporting the claim. If a state post-conviction case may affect a federal deadline, confirm whether it qualifies for statutory tolling; a filing generally must be properly filed and pending to pause the federal limitation period.
Do not assume that attorney discussions, requests for records, or an appeal for discretionary review automatically stop the clock. Seek qualified legal advice promptly, especially when the deadline is uncertain or close. The time limits for filing post-conviction motions can be strict, and exceptions depend on the governing law and facts.
