AEDPA changes the question after a state merits decision
A federal court considering a petition under 28 U.S.C. §2254 does not simply decide whether it agrees with the state court. When the state court adjudicated the federal claim on the merits, §2254(d) restricts relief unless the decision satisfies one of the statute's demanding exceptions.
Section 2254(d)(1) addresses legal error. It asks whether the state adjudication was contrary to, or involved an unreasonable application of, clearly established federal law as determined by the Supreme Court of the United States. Section 2254(d)(2) separately addresses an unreasonable determination of the facts. The two paths should not be blended together.
Clearly established law comes from Supreme Court holdings
For §2254(d)(1), the governing law comes from the holdings of Supreme Court decisions—not lower-federal-court precedent and not language that was unnecessary to the Supreme Court's result. Circuit decisions can help explain an issue or show how courts have applied a rule, but they do not themselves create clearly established federal law for this test.
The relevant Supreme Court law is measured as of the state court's adjudication on the merits. A later decision may explain existing law, but a petitioner cannot ordinarily use a rule first established after the controlling state decision to show that the earlier adjudication violated §2254(d)(1).
The contrary-to clause covers a direct legal conflict
Williams v. Taylor explains that a state decision is contrary to clearly established Supreme Court law when it applies a rule that contradicts the governing rule announced by the Supreme Court. The clause also reaches a materially indistinguishable case in which the state court arrives at a result different from the Supreme Court's result.
That inquiry requires precision. The petition should identify the controlling holding, the state court's stated rule, and the point of direct conflict. A disagreement with the state court's characterization of evidence is not automatically a contrary-to claim, and a case with materially different facts may belong under the unreasonable-application analysis instead.
An unreasonable application is more than an incorrect one
A state court can identify the correct governing principle and still apply it unreasonably to the facts. But Williams makes clear that an unreasonable application of federal law is different from an incorrect application. A federal court may not grant the writ merely because it would have reached a different answer on independent review.
Harrington v. Richter describes the boundary in demanding terms: relief remains unavailable while fairminded jurists could disagree about the state court's conclusion. Even a strong claim under ordinary merits review does not by itself establish that the state adjudication crossed §2254(d)(1)'s line.
The specificity of the Supreme Court rule affects the analysis
A broad constitutional standard can permit a wider range of reasonable applications. Richter explains that the more general the rule, the more latitude courts have in resolving particular facts. A narrowly defined Supreme Court holding can leave less room for disagreement.
White v. Woodall adds an important limit: if a federal court must extend a Supreme Court rationale before it governs the facts at hand, the proposed rule generally was not clearly established for §2254(d)(1). The absence of a case with identical facts is not always fatal, but the petition must show that the result follows from an existing holding rather than a new doctrinal step.
The state decision and the claim's posture must be identified first
Before applying §2254(d)(1), the federal court must identify whether the claim was adjudicated on the merits and which state decision supplies the reasoning. A reasoned appellate decision, an adopted lower-court ruling, and an unexplained denial can require different analytical steps under Supreme Court precedent.
The claim must also be the same federal claim fairly presented to the state courts. Changing the constitutional theory, supplying a materially different factual basis, or relying on evidence never placed before the state merits court can create exhaustion, procedural-default, and record-limit problems separate from §2254(d)(1).
The record should connect each state-court conclusion to the governing holding
A persuasive petition does not stop after quoting AEDPA's standard. It shows exactly what the state court decided, what evidence was before that court, which Supreme Court holding controlled at that time, and why every reasonable defense of the state result fails.
Cullen v. Pinholster generally limits §2254(d)(1) review to the record that was before the state court that adjudicated the claim on the merits. That makes state-court record development critical. Evidence first gathered in federal court cannot automatically be used to prove that the earlier state adjudication was unreasonable on the record it possessed.
Opening the §2254(d) gate does not finish the habeas case
Satisfying §2254(d)(1) removes AEDPA's relitigation barrier for the claim; it does not automatically direct release, a new trial, or another remedy. The petitioner still must establish the underlying federal violation and satisfy any other applicable limits, including exhaustion, procedural default, timeliness, harmless-error doctrine, custody, and remedy requirements.
The analysis should therefore separate three questions: what constitutional rule governs, why the state adjudication satisfies §2254(d)(1), and why the proven constitutional violation warrants relief under the remaining standards. Collapsing those questions can leave an otherwise substantial claim incomplete.
Build a claim-specific AEDPA chart before drafting
Section 2254(d)(1) is easier to analyze when the state and federal authorities are placed side by side. A useful review should organize the following material.
- The exact federal claim and each place it was presented in the state courts.
- Every reasoned state decision, incorporated ruling, summary denial, and relevant mandate.
- The Supreme Court holding in effect when the state merits adjudication occurred.
- The rule the state court actually applied and any materially indistinguishable Supreme Court facts.
- The state-court record supporting and contradicting each material conclusion.
- Whether the theory is contrary to, an unreasonable application of, or instead an unreasonable factual determination under §2254(d)(2).
- Any exhaustion, default, timeliness, record-development, harmless-error, or remedy issue that remains after §2254(d).
The difference between wrong and unreasonable controls
Section 2254(d)(1) preserves federal review for extreme legal errors while requiring substantial deference to state merits adjudications. The decisive issue is not whether another judge could write a better opinion. It is whether the state result conflicts with an existing Supreme Court holding in a way the statute recognizes and no fairminded jurist could defend.
