The Critical-Stage Test
Passing the attachment gate establishes that a criminal prosecution exists. It does not say which events inside that prosecution require a lawyer, because the Sixth Amendment does not place counsel at every step the government takes once charges are pending. Building on the attachment rule in Kirby, United States v. Ash states the working standard: the right to counsel attaches at those stages of the prosecution where the absence of counsel “might derogate from the accused's right to a fair trial,” and the start of adversary proceedings does not turn every later event into such a stage.1 That standard organizes the rest of this chapter. It is framed around trial fairness because the guarantee exists to protect the defense, so counsel is required where the defense could be damaged and is unnecessary where a lawyer could change nothing.
The guarantee reaches events before trial because of how criminal cases are now built. In United States v. Wade the Court observed that when the Bill of Rights was adopted there were no organized police forces as we know them, so the accused met the prosecutor and the witnesses at trial, where the evidence was marshalled. Modern law enforcement instead produces pretrial confrontations whose results may settle the accused's fate and reduce the trial itself to a formality.2 The Court answered by reading the promise of counsel “for his defence” to cover counsel's assistance whenever it is needed to assure a meaningful defense, wherever in the process that need arises.3 Wade was not the first step in that direction. Powell v. Alabama had already described the period from arraignment to trial as perhaps the most critical in a case, Hamilton v. Alabama required counsel at an arraignment where defenses could be lost, and Massiah v. United States excluded statements that federal agents obtained from the accused through an arranged meeting held without notice to his lawyer.4
In applying the standard, the Court looks at three features of an event. They are best read as three views of a single question: does the event expose the accused to the government's case in a way that a lawyer could make fairer and that the trial cannot later repair?5 The first feature is whether the event is a trial-like confrontation, one in which the accused faces the procedural system or an expert adversary. A layperson in that position is poorly equipped to notice what matters, and the lawyer's role is to supply what the Court has called “the guiding hand of counsel.”6 Where the accused is not even present, there is nobody for the lawyer to guide.
The second feature is whether rights or defenses can be lost at the event. If the accused must make a choice at that moment, and the choice cannot be undone later, then a lawyer who arrives after the fact arrives too late. The Court put the concern this way when it required counsel at an Alabama arraignment: what happens there may affect the whole trial, and available defenses may be irretrievably lost if they are not asserted then and there.7 Because the harm lies in the loss of a choice, the inquiry looks at what the event puts at risk. It does not ask whether the accused can later prove that a particular defense would have been raised, a point the next section develops.8
The third feature is whether any resulting unfairness could later be reconstructed at trial. Suggestion at a pretrial confrontation leaves little trace. A witness who has been steered toward one person at a pretrial event will tend to repeat that choice in the courtroom, and the defense lawyer at trial can cross-examine only on what the record reveals. An accused who had no lawyer at the earlier event therefore has no means of exposing the suggestion, and loses the main way of attacking the witness's later testimony. This is why the Court treated counsel at the lineup as necessary to protect the accused's right to a trial at which the witnesses against him can be meaningfully cross-examined.9 A lawyer's presence either prevents the prejudice or preserves the means of proving it, and that is the sense in which counsel's presence is needed to mount a meaningful challenge later.10
The contrast between two post-indictment identification events shows how the features sort cases. In Wade the accused had been indicted and was placed in a court-ordered lineup, wearing tape on his face and speaking words attributed to the bank robber, with no notice to his appointed lawyer, and the Court held the lineup a critical stage.11 The accused stood physically before the witnesses under the government's control, and any suggestiveness in the procedure was hard to reconstruct at trial. In Ash the accused had also been indicted and arraigned, but the event was a display of photographs to witnesses outside his presence, and the Court held it was not a critical stage.12 The timing was the same in both cases, so the difference lies in the event. With the accused absent there was no possibility that he would be misled by his unfamiliarity with the law or overpowered by his professional adversary.13
Because the label follows the risk, in practice the Court has fixed it largely by example. All in-court proceedings after the right attaches, including pretrial hearings, trial, and sentencing, count as critical, and so do post-charge lineups, while government witness interviews and photo identification procedures do not.14 The same logic implies that a procedure redesigned so that the danger of abuse disappears would leave a lawyer with nothing to guard against, so the status of a stage depends on what can go wrong there. The edges of the test are contested, as the discussion of photographic displays below shows. Students lose points here when they treat every event after charge as one that requires counsel, and the next three sections test the standard on arraignment, lineups and showups, and photo displays.
