Sudo doesn't do restrictions.

You could write a limited version of chmod, and only let them run
that, (hide/change permissions on the real chmod) but that still
wouldn't need the involvement of sudo.  And it would be a lot of
hard to maintain stuff.

And anyway, they could still write their own chmod command in C,
or perl, or python or's not hard.

If you cared to restate your problem, maybe I could help a little
more.  What I think you might need is what's known as MAC --
mandatory access control, and that just doesn't come in any
standard commercial operating system.  There might be Linux
kernel modifications / modules to do it though.
