|*These were all capital crimes; the usual sentence was death. From 1547 if a peer or peeress was convicted of a crime, except treason or murder, he or she could claim "privilege of peerage" to escape punishment if it was their first offence. In all, the privilege was exercised five times, until it was formally abolished in 1841.|
