+## <a id="codeOwnersSubmitRule">Code Owners Submit Rule
+
+The logic that checks whether a change has sufficient [code owner
+approvals](#codeOwnerApproval) to be submitted is implemented in the code owners
+submit rule. If the code owners submit rule finds that code owner approvals are
+missing the submission of the change is blocked. In this case it's possible to
+use a [code owner override](#codeOwnerOverride) to unblock the change
+submission.
+
+**NOTE:** Besides the code owners submit rule there may be further submit rules
+that block the change submission for other reasons that are not related to code
+owners.
