let's say that we have this situation :
-rwxrwx-w- 1 user1 mygroup 0 Sep 12 16:53 testfile
Can a sudoer change this file ownership ? does he have to be a sudoer on command chown or on file ?

I missed the point that
the ownership of any file in the system may only be altered by a super-user.The 2nd set of rwx shows that any user who is a member of
mygroupcan read, write and execute this file.So, if the user
user2is a super-user (present in sudoers and have sufficient permissions), he can make the necessary changes. If not, then he / she can't modify the ownership!
