I have had a decent look through the RT system and I cannot see any
permissions on the people that can resolve tickets.
We run a software development process through RT and only want the
originator of the ticket or admin to be able to resolve the ticket when
they are 100% happy with it.
Currently, we have coped by having a scrip to create an approval ticket
when a new ticket is created. In this way, the new ticket cannot be
resolved until the approval ticket is resolved.
We would rather have the permissions options rather than the approval
