Thanks for your bug report. This isn't a bug in the Ubuntu distribution, but is the permissions set with Launchpad. The priority field for specifications is set by the core developers to prioritise what is considered to be most important for the distribution, therefore people who submit specifications cannot set the priority of the specification for the distribution themselves.
** Changed in: Ubuntu Status: Unconfirmed => Rejected -- Unable to change priority in a specification https://launchpad.net/bugs/53523 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
