466 U.S. 648 (1984)
In 1975, William Cronic served as president and controlling shareholder of a company that manufactured keying devices marketed under the name Sentry Manufacturing Company.1 The company entered into a contract to sell devices to a New York customer, but after checks were returned for insufficient funds, the company went out of business.2 In 1978, a federal grand jury indicted Cronic and two codefendants for mail fraud based on a scheme to defraud the customer using the mails.3
The two codefendants pleaded guilty, while Cronic pleaded not guilty and was tried before a jury in the Western District of Oklahoma.4 Twenty-five days before trial, the district court appointed an attorney who had never tried a criminal case, assisted by two inexperienced associates.5 The four-day trial featured testimony from nineteen government witnesses and none from the defense, leading to Cronic's conviction on eleven of seventeen counts and a twenty-five-year sentence.6
Cronic appealed to the United States Court of Appeals for the Tenth Circuit.7 The court reversed the conviction, finding that the short preparation time, counsel's inexperience, the gravity of the charges, and the case's complexity created a presumption that counsel's performance was prejudicially ineffective, without identifying any specific errors.8 The Supreme Court granted the government's petition for certiorari to review this categorical presumption.9
Whether the Court of Appeals erred by presuming that the circumstances of counsel's appointment and preparation denied the respondent the effective assistance of counsel without identifying any specific errors or actual prejudice?10
The Sixth Amendment right to the effective assistance of counsel is recognized not for its own sake but because of the effect it has on the ability of the accused to receive a fair trial.11 Absent some effect of challenged conduct on the reliability of the trial process, the Sixth Amendment guarantee is generally not implicated.12 The Court has recognized circumstances so likely to prejudice the accused that the cost of litigating their effect in a particular case is unjustified.13 In those circumstances, the defendant need not show that counsel’s performance had an actual adverse effect on the defense.14 The Court has identified three such circumstances.15 First, if the accused is denied counsel at a critical stage of the trial, prejudice is presumed.16 Second, if counsel is prevented from assisting the accused during a critical stage, prejudice is presumed.17 Third, if counsel has an actual conflict of interest that adversely affects the defense, prejudice is presumed.18 In all other cases the defendant must demonstrate deficient performance and actual prejudice.19
Yes. The circumstances identified by the Court of Appeals, including the time afforded for investigation and preparation, the experience of counsel, the gravity of the charges, and the complexity of the case, do not fall into the category of situations where prejudice is presumed.20 In the established facts the attorney was appointed twenty-five days before trial yet filed pretrial motions, interviewed witnesses, and otherwise prepared for trial.21 The defense theory remained a simple one that the respondent did not have the intent to defraud.22
The inexperience of counsel supplies no basis for a presumption because every lawyer begins practice somewhere.23 The charges here were not so complex that twenty-five days of preparation was inherently inadequate.24 The proper standard therefore requires the respondent to identify specific errors by counsel and to demonstrate actual prejudice under the two-prong test.25
The judgment of the Court of Appeals is reversed and the case is remanded for further proceedings consistent with this opinion.26
