How to read the chart
These paths can branch, overlap, or close.
Direct appeal ordinarily focuses on errors shown in the trial-court record. Collateral review may address recognized claims that require facts outside that record, but it is governed by statutes of limitation, waiver, exhaustion, procedural default, and restrictions on later petitions.
Sentence-modification authority must come from a statute or rule. Clemency is discretionary executive mercy rather than another round of judicial review. The right path depends on the judgment, jurisdiction, dates, issues already raised, prior filings, and available evidence.
The Supreme Court is not an automatic final appeal.
A petition for a writ of certiorari asks the U.S. Supreme Court to exercise discretionary review. It is not a new trial and does not allow every losing party another appeal. In state cases, a federal question and the procedural history of that claim are especially important.
