Criminal Procedure

Criminal Procedure is the area of constitutional law that governs how the government investigates, charges, and tries people suspected of crimes, enforcing limits drawn mainly from the Fourth, Fifth, and Sixth Amendments. It defines the rules for searches, seizures, interrogations, the right to counsel, and a fair trial.

What Criminal Procedure covers

Criminal Procedure covers the constitutional constraints on police and prosecutors from the moment of investigation through trial and appeal. On exams it is tested almost entirely as federal constitutional doctrine: the Fourth Amendment's protection against unreasonable searches and seizures and its remedy, the exclusionary rule; the Fifth Amendment's privilege against self-incrimination, the Miranda warnings, and the bar on double jeopardy; and the Sixth Amendment's rights to counsel, confrontation, a speedy and public jury trial, and compulsory process. The MBE tests these doctrines as fact-pattern application questions, and essays ask you to spot which amendment is implicated, state the governing rule, and resolve standing, warrant requirements, exceptions, and remedies. Mastery means knowing the triggers, the exceptions, and the consequences of a violation cold, because the answers turn on small factual distinctions.

Key topics

Fourth Amendment - Search & Seizure
A government search that intrudes on a reasonable expectation of privacy generally requires a warrant supported by probable cause unless a recognized exception applies, and evidence obtained in violation is subject to the exclusionary rule.
Fourth Amendment - Arrest & Stop
An arrest requires probable cause, while a brief investigatory stop and a limited frisk for weapons require only reasonable, articulable suspicion under Terry v. Ohio.
Fifth Amendment - Self-Incrimination
A suspect in custodial interrogation must receive Miranda warnings, and a statement obtained without them, or compelled testimony against oneself, is generally inadmissible in the prosecution's case-in-chief.
Fifth Amendment - Double Jeopardy
The Double Jeopardy Clause bars a second prosecution for the same offense after acquittal or conviction and bars multiple punishments for the same offense, with offenses treated as the same unless each requires proof of an element the other does not under Blockburger.
Sixth Amendment - Right to Counsel
The Sixth Amendment guarantees the assistance of counsel at all critical stages once formal charges are filed, and it is offense-specific, distinct from the Fifth Amendment Miranda right to counsel during interrogation.
Sixth Amendment - Confrontation
The Confrontation Clause bars admission of testimonial hearsay against a criminal defendant unless the declarant is unavailable and the defendant had a prior opportunity to cross-examine, under Crawford v. Washington.
Pretrial & Trial Rights
A criminal defendant is entitled to a speedy and public trial, an impartial jury, the presumption of innocence with proof beyond a reasonable doubt, and the prosecution's disclosure of material exculpatory evidence under Brady v. Maryland.

Practice Criminal Procedure with LawCoach

LawCoach helps you turn Criminal Procedure rules into exam points by letting you practice in the formats the bar actually uses. You can drill MBE-style multiple-choice questions on search and seizure, Miranda, and confrontation to test whether you can apply the rule to a fact pattern under time pressure, and write MEE-style essays and MPT-style performance tasks that force you to spot the right amendment, state the rule, and resolve exceptions and remedies. Paid essay answers are graded by a five-specialist reviewer panel covering issue-spotting, rule accuracy, application and analysis, structure and exam strategy, and counterargument and calibration, with a synthesizer that combines the feedback; free essays receive a three-reviewer panel. As you practice, LawCoach tracks which topics are weak, so if you keep missing standing or the exceptions to the warrant requirement, it surfaces that and points your study plan there next. LawCoach is an educational study tool, not legal advice, and its AI feedback can contain inaccuracies.

Frequently asked questions

What is the difference between the Fifth and Sixth Amendment right to counsel?
The Fifth Amendment right to counsel, from Miranda, attaches during custodial interrogation and must be invoked by the suspect; once invoked, police must stop questioning until counsel is present. The Sixth Amendment right to counsel attaches automatically when formal charges are filed and applies to all critical stages, but it is offense-specific, meaning it covers only the charged crime. The two rights have different triggers, scope, and waiver rules, which is why exam questions often turn on which one applies.
When can police conduct a search without a warrant?
Police may search without a warrant when a recognized exception to the warrant requirement applies, such as a search incident to a lawful arrest, exigent circumstances, a valid consent, the automobile exception with probable cause, the plain-view doctrine, or a Terry stop-and-frisk for weapons. Each exception has its own scope and limits, and exceeding that scope can make the search unreasonable. If no exception applies, a search of an area protected by a reasonable expectation of privacy generally requires a warrant supported by probable cause.
What is the exclusionary rule?
The exclusionary rule bars the prosecution from using evidence obtained in violation of the Fourth, Fifth, or Sixth Amendment in its case-in-chief. It also reaches derivative evidence as fruit of the poisonous tree, though exceptions such as independent source, inevitable discovery, attenuation, and good-faith reliance on a warrant can allow admission. The rule is a judicially created remedy designed to deter unconstitutional police conduct rather than to remedy every error.
How is Criminal Procedure tested on the bar exam?
Criminal Procedure is tested as federal constitutional doctrine on both the multiple-choice (MBE) and written portions of the bar exam. MBE questions present short fact patterns and ask you to apply rules on search and seizure, Miranda, and trial rights, while essays ask you to identify the constitutional issue, state the governing rule, and resolve warrant requirements, exceptions, and remedies. Strong answers lead with the correct rule and then apply it precisely to the facts.
