regarding the Good Friday Agreement
Regarding the Good Friday Agreement, aka The Belfast Agreement on the Good Friday Agreement, don't take my word for it look at it for yourself . it's freely available online at Irish Department of foreign affairs/ the UN /the British Government/ and many other places, in searchable pdf format you can search for "majority" & see if its defined ( I can't see any definition ) you can search for "percent" & see if it is used (I can't find any) you can search for the symbol " % " and see that it is used twice 60% and 40%. But that is not regarding a border poll. Never-the-less it is the only place in the agreement where a majority is quantified. in my view that 60/40 is the "spirit" of the agreement as to majority -v- minority in the absence of any other definitions please read it yourselves don't heed the spin politicians from here or abroad source example:- https://www.dfa.ie/media/dfa/alldfawebsitemedia/ourroles
