Really messed up having something so far reaching and giving it such an innocuous name a normal person couldn't possibly understand the implications of. Definitely an evil mind behind that one.
And (Norman) French was the official legal language of England from 1066 to 1362, at a time it wasn't even the official language of France itself (that only happened in 1539 with the ordinance of Villers-Cotteret replacing Latin in legal documents).
To this day some ceremonials of Parliament like the King's Assent to promulgate legislation are still in Norman French.
