Claims have been rejected that a publicly elected Legislative Council from eight constituencies would create a group of 'Super MHKs'.
Members were debating the clauses of Martin Quayle's private members bill.
Opposing the 8 constituency option, Tony Brown said it would lead to conflict and mayhem and destroy 1000 years of history.
Mr Brown claimed that LEGCO members with much larger constituencies would lead to a more powerful body than the House of Keys
Despite strong opposition the 8 single seat option was approved by 12 votes to 11.
