New laws are always being created and old ones updated to deal with the needs of a constantly changing society. In Britain, Parliament if arguably the most important lawmaking body since Statute Laws are created once a nominated Bill has passed through both the House of Commons and the House of Lords and has then been given Royal Assent.
Having been democratically elected, the Government then has a mandate from the people to act as their representative and so there is no need for public consultation about every law that the Government wishes to enact. Given the vast numbers of laws that are created or amended every year, full public consultation on every one of them would be a next to impossible task.
