British law != UK current law but those laws that in the distant past were direct descendents of UK law at the time.

British law vs say Roman law.

Because of the widespread nature of the British empire remnants of these laws (and remnants of the Empire, such as the Queen being formally the supreme being in Canada) are still found all over the world, even if a lot of those laws have been abolished in the UK itself.

> British law vs say Roman law

I think you mean English common law. There's not such thing as "British law" as such, because Scotland has its own legal system (which incidently is partly based on Roman law).

Ah ok, I read that as "Those crazy Brits still have this" and waded in to correct ;)

Those crazy Brits abolished it in 1753 according to WP:

So maybe they're not that crazy :)
