Smith v. Illinois

Background

A man convicted of selling heroin in a Cook County restaurant challenged his conviction on the ground that the trial judge would not let the defense ask the principal prosecution witness his true name or where he lived. The witness had identified himself initially as “James Jordan,” then admitted that was not his real name. Police officers testified about marked money and the bag of heroin, but the crucial events inside the restaurant were disputed and turned on who the jury believed.

Reasoning

The Court asked whether refusing the defense permission to learn and question the witness’s real identity and address denied the accused the basic right to confront and cross-examine the witnesses against him. Relying on earlier decisions, the Court explained that a witness’s name and address open ordinary lines of questioning and outside investigation that are essential to testing credibility. The Court held that barring those elementary inquiries effectively weakens the right to cross-examine, and that the denial here violated the defendant’s constitutional right to face and question witnesses, so the conviction was reversed.

Real world impact

The decision protects a defendant’s ability to ask basic identifying questions of prosecution witnesses in state criminal trials. Trial judges must not refuse routine name-and-address questions without a clear justification. The ruling sends disputes about limiting such questioning back toward careful judicial review of the reasons for exclusion.

Dissents or concurrances

A concurring Justice agreed with reversal but said the State should be allowed to show safety or other reasons before such questions are barred. A dissent argued the record suggested the defense already knew the information and that the error, if any, was harmless.
