Right, but this is not a black-and-white situation IMO.
Reviewers may overlook things even though they do their best and I guess that
happens to everyone occasionally.
One way to look at code review is as advice in a decision making process.
Of course, you are more likely to listen to people who tend to give you good
advice, but then they may not be right this time around and the decision
is for you to make anyway.

I would be very careful about setting rules like that unless you absoultely
believe that you'll never need to break them, whatever the reason.
OTOH if people realize that doing review generally helps their patches to be
accepted, that may actually work. :-)

There needs to be a clear benefit for the reviewer and ideally such that can
be presented to their management as a good deal. Today, the perceived value
of code changes going in is much higher and people allocate their time
