I am trying to understand the subtle distinction my colleague is raising.
If we go back to subclause 22(1) or subclause 22(4), we are still talking about reasonable grounds.
If I correctly understand the part concerning the senior officer's agreement, the senior officer must ensure that "the preclearance officer or border services officer, as the case may be, is authorized under the applicable section to conduct the search."
The senior officer will surely ask the officer or junior officer why he or she wants to search a particular person. The latter must then justify his or her decision under subclause 22(1) or 22(4). In my view, the amendment Ms. May proposes is already in the bill.
Those are my comments. I may be mistaken.
