Firstly Steve, you said "We refused" Devolved powers. By We, do you mean the English? If so, we have never been asked.
Moving on, as Bob pointed out, mostly correctly, there's a difference between Scots and England & Wales legislation. Yet the Scots vote on ours, the reverse does not apply. Now thats not just Criminal Legislation, it's civil as well as enabling legislation on purely English matters. So for example PCC's, which I hope will soon disappear, Scots voted on, but don't have. Likewise on the NHS, Scots MP's vote on anything to do with that, yet don't have the use for it, Scotland having it's own.
No one has suggested it's the Scot's fault, it's a historical hangover, but under Labour it's never going to go away, they have too many MP's from Scotland, so it's unlikely they could successfully object to E&W legislation successfully. But you surely know that.
Of course Scots MP's should be involved in defence and foreign policy. Depending on how Tax raising powers end up in Scotland, also on economic issues. But if Scotland for example sets it's own spending and tax raising, then why should they be involved in the same for England?
