How to speak Lawyer

'Section 13 abolished the common law offences of champerty and barratry, challenging to fight, eavesdropping or being "a common scold or a common night walker." It also repealed the offence of praemunire, which had survived on the statute books since 1392. It preserves the common law offence of embracery'
