Look it up in Wikipedia! ;) [http://en.wikipedia.org/wiki/Chown]

It often helps to look at the documentation for system calls; if I look at
the man page for the chown system call -  man 2 chown  - which the chown
program will call at some point during its execution, it says: "Only a
privileged process (Linux: one with the CAP_CHOWN capability) may change
the owner of a file."

I'll confess to not knowing anything about capabilities, however. In this
case I'll assume that only processes with an effective uid of 0 have
this capability.
