Laws actioned in error? Very apprehensive (2,1,4,5)

I believe the answer is:

in a cold sweat

'very apprehensive' is the definition.

'laws actioned in error?' is the wordplay.
'in error?' is an anagram indicator (I've seen 'in error' mean this).
'laws'+'actioned'='lawsactioned'
'lawsactioned' anagrammed gives 'IN A COLD SWEAT'.

I've seen this clue in The Independent.
