Black cap

English judges' cap

The black cap is a plain black fabric square formerly worn as symbolic headgear by English, Welsh, Irish and Northern Irish judges in criminal cases when passing a sentence of death. When worn, the square was placed on top of the judicial wig, with one of the four corners of the fabric facing forward. The cap is based on Tudor court styles. Originally, the cap was a normal part of judicial full dress, as worn by judges on all especially formal or solemn occasions, of which passing a death sentence was just one.
