A judge issues a writ of habeas corpus to review the legality of someone's detention, ordering the custodian (like a prison official) to bring the person to court and prove they are being held lawfully, often used when someone claims unlawful imprisonment, violation of constitutional rights, or challenges a conviction/sentence, including issues like ineffective legal counsel, new evidence of innocence, or unconstitutional conditions, and it's a fundamental safeguard against arbitrary state power, applicable in criminal, immigration, and sometimes child custody matters.
