Allan C myself and my fellow countrymen did exercise their democratic right on the 18th of September last year - they voted for Scotland to remain as part of the United Kingdom - question is why don't you and the Scottish Nationalist party accept that as your erstwhile leader loudly proclaimed that he would do?

"Westminster simply realised it had no option other than transfer the authority to the Scottish gvt" - NO

Following what existing precedent? The granting of temporary powers? I take it that you do know what the word temporary means?

The Scottish Parliament can hold a non binding referendum on anything they want to for that referendum to affect the make up of the United Kingdom, the country that we presently all live in then the referendum must be sanctioned by the Queen and her Parliament in Westminster.

"The precedents were set with the acceptance first that Northern Ireland can leave whenever it wants" - Complete and utter twaddle Allan C and you know it. The arrangement with Northern Ireland would be a call for a referendum that would then have to be agreed to with Westminster. There would then be consultations between Stormont, Westminster and Dublin and the options on the referendum paper would be agreed (Likely options would be - 1: Remain as part of the UK; 2: Unite with the Republic of Ireland; 2: Full independence). Should the vote go for unification with the Republic of Ireland then a referendum has to take place in the Republic of Ireland to establish that it is the will of the people there for the union to take place - it is not just up to the electorate or the Assembly in Northern Ireland as you seem to imagine, not by a long shot.
