(From a UK perspective, though I now live in the USA): Can anyone think of a recent situation where the UK government has given back a power it has temporarily taken? This is a genuine question - I cannot. The closest was a stand taken by David Davis against 90-day detention without charge during the Blair administration (though he has since proved rather more illiberal than this position would suggest). In the UK at least, while it might not _have_ to work that way, in practice it does.
