# Instance-level merge request approval rules **(PREMIUM ONLY)**
|
||
|
||
> Introduced in [GitLab Premium](https://gitlab.com/gitlab-org/gitlab/issues/39060) 12.8.
|
||
|
||
Merge request approvals rules prevent users overriding certain settings on a project
|
||
level. When configured, only administrators can change these settings on a project level
|
||
if they are enabled at an instance level.
|
||
|
||
To enable merge request approval rules for an instance:
|
||
|
||
1. Navigate to **{admin}** **Admin Area >** **{push-rules}** **Push Rules** and expand **Merge
|
||
requests approvals**.
|
||
1. Set the required rule.
|
||
1. Click **Save changes**.
|
||
|
||
GitLab administrators can later override these settings in a project’s settings.
|
||
|
||
## Available rules
|
||
|
||
Merge request approval rules that can be set at an instance level are:
|
||
|
||
- **Prevent approval of merge requests by merge request author**. Prevents project
|
||
maintainers from allowing request authors to merge their own merge requests.
|
||
- **Prevent approval of merge requests by merge request committers**. Prevents project
|
||
maintainers from allowing users to approve merge requests if they have submitted
|
||
any commits to the source branch.
|
||
- **Prevent users from modifying merge request approvers list**. Prevents project
|
||
maintainers from allowing users to modify the approvers list in project settings
|
||
or in individual merge requests.
