:: Hello - to put this in context, the discussion arose in Talk:Home Rule Act 1914 when  reverted my addition of "(officially the Government of Ireland Act 1914)" in the lead section.  I entirely accept that the most common name is "Home Rule Bill" but I wanted to make sure that the official short title was mentioned somewhere. 

 :: I don't have particularly strong opinions about where the articles should be, since redirects will take care of all of the references.  In the absence of the specific MoS policy, I would go with the general rule, that an article should be at its most common name, in this case Home Rule Bill (or equivalent).  However, I can see that it makes good sense for legislation to be located at its official name (which, in this context, is the short title rather than the long title) with appropriate redirects.  Having said that, the Parliament Acts are at Parliament Act, not Parliament Act 1911 or Parliament Act 1949.
