Pate said the Freemen want a "guarantee of free passage" for one or two of their members to leave the compound and help set up a "common law grand jury" to determine if they have broken any laws.
In seeking to legislate on the matter, Lib Dem peer Lord Thomas of Gresford said ministers were refusing to "trust the good common sense of a British jury".
The jury soon became standard in criminal and civil cases at common law, and its use spread with the British empire, nowhere more so than in the American colonies.
