Regarding authoritarian charged for restraint used (11)

I believe the answer is:

restriction

I'm a little stuck... Click here to teach me more about this clue!

'restraint used' is the definition.
I can't judge whether this definition defines the answer.

'regarding authoritarian charged' is the wordplay.
'regarding' becomes 're' (re can mean regarding, concerning).
'authoritarian' becomes 'strict' (I've seen this before).
'charged' becomes 'ion' (I've seen this in other clues).
're'+'strict'+'ion'='RESTRICTION'

'for' is the link.

Can you help me to learn more?

(Other definitions for restriction that I've seen before include "Limitation" , "Limiting condition" .)

I've seen this clue in The Irish Times.
