I was reading about the Edwards v Canada (AG) case on Wikipedia, and in the petition put forward by her and the other famous five to the federal government I read the following sentence:
I. Is power vested in the Governor-General in Council of Canada, or the Parliament of Canada, or either of them, to appoint a female to the Senate of Canada?
My question is this; does the clause "or either of them" contribute anything to the sentence?
I was wondering if it might be meaning "both" in this instance, but at least according to this site, which was one of the top results on Google when trying to find out if that is a valid use, "it means (...) one or the other, but not both of them simultaneously"
