The constitutional right to confront one’s accusers in criminal court and have them cross-examined under penalty of perjury
The Confrontation Clause of the Sixth Amendment requires that in all criminal prosecutions, the accused shall have the right to confront the witnesses against him and to have counsel cross-examine them under oath.
From this right came further rights, such as the right to compel the presence of one’s own witnesses in support of the defendant’s case.
