Place legal restrictions on container port (4,4)

I believe the answer is:

bind over

'place legal restrictions on' is the definition.
(legal term)

'container port' is the wordplay.
'container' becomes 'bin' (bin is a type of container).
'port' becomes 'dover' (English port).
'bin'+'dover'='BIND OVER'
