Lawyers are rather fond of such doublets and triplets. Consider free and clear, null and void, terms and conditions, and even law and order. The origin of a lot of legalisms is the historical confusion over language in ancient English courts: Latin, French, or English? Most odd legal grammar is actually of French origin.

It's one of my favourite lists: https://en.wikipedia.org/wiki/Legal_doublet

It seems to be missing "aid and comfort" (from the clause of the U.S. Constitution about treason). Not sure if this is used anywhere else, but it seems similarly redundant from my non-lawyer perspective, in that if were only "aid" and not comfort, it seems absurd that it would be functionally different

> A legal doublet is a standardized phrase used frequently in English legal language consisting of two or more words that are near synonyms.

...

> power and authority

Should that really be on the list? Power is the capability to do something, authority is the permission to do it. Sometimes power and authority are near synonyms, such as in frontier areas with little government, but generally in a functioning, civilized society they are quite distinct.
