File Info, under Sharing & Permissions, says "You have custom access" and lists:

Name          Privilege
joe (user)    Read & Write
staff (group) Read & Write
everyone      Read only

But ls -le says:

-rwxrwxr-x  1 egbert  staff  22806528 Jun  4 08:57 somefile.ext

This agrees with output from stat -x somefile.ext

Mode: (0775/-rwxrwxr-x) Uid: (  501/ egbert)  Gid: (   20/   staff)

joe is not a known user on this system (check with dscl . -list /Users UniqueID and "joe" is not in the list)

Finder won't let me "Choose new owner...". It says "The operation can't be completed because you don’t have the necessary permission." Yet I am egbert (see above) and I am owner and I have write privileges.

There does not appear to be any ACL on the file or any extended attributes (@ or +). sudo chmod -N somefile.ext fails with chmod: Failed to clear ACL on file somefile.ext: Operation not supported.

So who is joe if he's not known or listed among users? And how do I remove this user's access and restore privileges to me (egbert)? And why is there a disagreement between the Finder and what is reported by ls and stat?

    Have you tried repairing permissions in disk utility? And sometimes file permissions will carry over between computers and if your computer is accessed over the network – Alex Jun 5 '14 at 1:19
