6.3.2.4 CLIMB CLEARANCE ABOVE LEVELS SPECIFIED IN A SID
When a departing aircraft on a SID is cleared to climb to a level higher than the initially cleared level or the level(s) specified in a SID, the aircraft shall follow the published vertical profile of a SID, unless such restrictions are explicitly cancelled by ATC.
6.5.2.4 DESCENT BELOW LEVELS SPECIFIED IN A STAR
When an arriving aircraft on a STAR is cleared to descend to a level lower than the level or the level(s) specified in a STAR, the aircraft shall follow the published vertical profile of a STAR, unless such restrictions are explicitly cancelled by ATC. Published minimum levels based on terrain clearance shall always be applied.
This is what I would expect. The restrictions remain unless cancelled. I'm not sure why you would have published restrictions if you need to restate them.
11.4.2.6.2.5 Level restrictions issued by ATC in air-ground communications shall be repeated in conjunction with subsequent level clearances in order to remain in effect.
This is not how it's done where I am. A subsequent restriction cancels a previous one (unless restated), but a subsequent level clearance does not.
Important things to standardise.
