How to Change Group Permissions

[Katherine Burkholder]

Is there a way to restrict a Group from being able to 'Close' issues on a particular project?

[Nic Brough -Adaptavist-]

Not really.  Jira tends to be permissive, rather than restrictive, so the approach is "grant permission to those who should have it, and don't give it to those who should not".

There are some tricks you can play with workflow properties, but they're a bit messy compared with a permissions review.
