OH AT Law common mistakes
OH AT Law · Understand the traps and how to avoid them.
On contract questions, spotting a possible contract formation issue and immediately analyzing offer, acceptance, and consideration in the abstract, without first identifying whether the question asks about formation, performance and breach, defenses, or remedies, and without asking which party the call of the question favors.
Bar-style contract prompts often include a formation fact pattern but actually test a later issue such as anticipatory repudiation, the perfect tender rule, or expectation damages. Candidates trained to look for offer and acceptance reflexively write a formation essay because that is the first framework they memorized, and the familiar facts create a false sense of recognition.
What to do instead
Before writing, underline the call of the question and the remedy requested, then state the governing issue in one sentence. If formation is not genuinely contested, note in a single line that a contract exists and move to the disputed element. Practice by reading the call first, then the facts, and drafting only a one-sentence issue statement before any analysis.
On hearsay questions, deciding admissibility solely by asking whether the out-of-court statement is offered for its truth, and stopping there, without completing the second step of checking whether a specific exclusion, exemption, or exception applies and which party needs the statement.
The truth-of-the-matter dichotomy is the most heavily drilled concept in evidence study, so candidates treat it as the whole test. They also lose track of the proponent's purpose and of the fact that statements offered to impeach, to show effect on the listener, or as verbal acts are not hearsay at all, while statements that are hearsay may still be admitted under a listed exception.
What to do instead
Use a fixed two-step checklist every time: first, is it a statement by a declarant offered for its truth; second, if yes, name the specific exception or exclusion by its elements and apply each element to the facts. Write the exception's name in the margin before analyzing it, and separately identify whether the statement is offered by the plaintiff or defendant and for what purpose.
On criminal procedure questions, analyzing a search or seizure under the Fourth Amendment without first establishing the government action, the defendant's standing and reasonable expectation of privacy, and whether the challenge is to a search, a seizure of a person, or an identification procedure.
Candidates jump straight to warrant exceptions such as consent, plain view, search incident to arrest, or exigency because those are the most memorable categories. They skip threshold questions like whether the defendant had a protected interest in the place searched, whether the actor was a private party or a government agent, and whether suppression is the requested remedy.
What to do instead
Open every Fourth Amendment answer with three sentences: state action, reasonable expectation of privacy in the place or thing searched, and the precise police conduct challenged. Only then apply the warrant requirement and any exception, and close by addressing the exclusionary rule, its exceptions, and whether the evidence would inevitably have been discovered.
On civil procedure questions, treating subject-matter jurisdiction, personal jurisdiction, and venue as interchangeable labels and analyzing only one of them, usually personal jurisdiction, when the facts raise all three or when the real issue is supplemental jurisdiction or removal.
The three concepts are taught together and share vocabulary about contacts, fairness, and forum, so under time pressure candidates collapse them. Questions involving a federal claim plus a state claim, or a case removed from state court, are especially likely to be misread as pure personal jurisdiction problems because the facts mention out-of-state parties.
What to do instead
Before analyzing, write three headings: subject-matter jurisdiction, personal jurisdiction, and venue. Under subject-matter jurisdiction, check federal question, diversity including complete diversity and amount in controversy, and then supplemental jurisdiction under the same case or controversy test with its discretionary limits. Address each heading even if briefly, and never let a personal jurisdiction discussion substitute for the jurisdictional analysis.
On constitutional law questions, reciting the tiers of scrutiny as labels, such as strict scrutiny or rational basis, without identifying the specific right or classification at issue and applying the correct test's elements to the particular facts.
Scrutiny labels are easy to memorize and feel like a complete answer, so candidates write that a law is subject to strict scrutiny and conclude it fails, without stating what the government must show, whether the law is facially neutral or discriminatory in effect, or whether a fundamental right or suspect class is actually implicated.
What to do instead
For each constitutional question, first classify the right or classification, then write the test in full with its elements, such as compelling interest, narrow tailoring, and least restrictive means for strict scrutiny. Apply each element to the named facts, and address the alternative test the other side would urge if the classification is contested.
On criminal law questions, conflating the mens rea required for the offense with the mens rea required for accomplice liability or for attempt, and treating mere knowledge, presence, or encouragement as sufficient for accomplice liability without finding intent to facilitate.
The Model Penal Code and common law mental states are taught as a single vocabulary, and fact patterns describing a bystander who knew about the crime invite the assumption that knowledge equals complicity. Candidates also forget that attempt requires specific intent to commit the target offense even when the completed crime requires only recklessness.
What to do instead
State the mental state for the completed offense, then separately state the mental state for the mode of liability charged. For accomplice liability, require purposeful conduct intended to aid or encourage, and analyze whether the principal's crime was a natural and probable consequence only if the jurisdiction uses that rule. For attempt, expressly note the specific intent requirement and then apply the substantial step or dangerous proximity test.
On contracts questions involving the Uniform Commercial Code, applying common law rules to a sale of goods, or the reverse, particularly on the mirror image rule, the perfect tender rule, and the statute of frauds, without first classifying the contract as goods, services, or a mixed transaction.
Most courses begin with common law formation and cover the UCC later, so the common law framework is more rehearsed and comes to mind first. Mixed contracts for goods and services also tempt candidates to skip the predominant purpose analysis and simply pick one body of law.
What to do instead
Make the first line of every contracts answer a classification sentence: identify the subject matter, apply the predominant purpose test to mixed contracts, and state which body of law governs. Then use only that body's rules, and where the UCC applies, expressly note the relaxed formation rules, the perfect tender rule and its cure provisions, and the UCC statute of frauds with its merchant confirmation exception.
On evidence questions about character evidence, analyzing whether the evidence is relevant and then admitting or excluding it without identifying the purpose for which it is offered, such as propensity, motive, intent, identity, or absence of mistake, and without applying the civil versus criminal and defendant versus victim distinctions.
Character evidence rules are layered and exception-heavy, and candidates try to recall a single rule instead of running the purpose-based analysis. They also forget that evidence offered for a non-propensity purpose is admissible even when it incidentally shows character, and that the prosecution may rebut a defendant's character evidence only in limited ways.
What to do instead
Write the purpose of the offer before applying any rule. If the purpose is propensity, state the general prohibition, then the criminal defendant and victim exceptions, and the civil case limits. If the purpose is non-propensity, name the specific purpose and confirm the evidence is relevant to an element in dispute, then address the Rule 403 balance.
On civil procedure questions about pleadings and pretrial motions, confusing the standards for a motion to dismiss for failure to state a claim with the standard for summary judgment, and analyzing the sufficiency of the complaint using evidence outside the pleadings.
Both motions test the legal sufficiency of a claim, and candidates remember the phrase that plausibility applies but forget that the motion to dismiss looks only at the complaint's allegations while summary judgment looks at the developed record and requires no genuine dispute of material fact. Questions that attach discovery facts invite the wrong standard.
What to do instead
Name the procedural stage first and state its standard in one sentence. For a motion to dismiss, evaluate only the allegations and reasonable inferences in the plaintiff's favor, and note that matters outside the pleadings convert the motion. For summary judgment, identify the material facts, ask whether a reasonable jury could find for the nonmovant, and address the burden-shifting framework.
On criminal procedure questions about confessions, treating Miranda warnings and the voluntariness of a confession as the same issue, and concluding that a statement is admissible merely because warnings were given or inadmissible merely because they were not.
Miranda is the most familiar doctrine in the area, so candidates use it as a complete answer. They overlook that due process voluntariness is a separate inquiry, that Miranda applies only to custodial interrogation by government agents, and that public safety, booking, and routine questions fall outside it.
What to do instead
Analyze in two separate paragraphs. First, determine custody and interrogation, then whether warnings were required and given, and whether the waiver was knowing, intelligent, and voluntary, including invocation rules. Second, independently assess whether the statement was voluntary under the totality of the circumstances regardless of warnings, and address the fruit of the poisonous tree and its exceptions.
