Rehiring After a Break: Should We Repeat Criminal Background Checks?

What should be the policy for background verification in case of rehire?

We have a rehire joining us after 10 months; however, there was no employment in between. We already have the verification done for education, address, and previous employments during the first time joining. Should we get the criminal/court checks done again? If yes, why? If no, why not?

Verification has no legal sanction. If you wish to conduct verification, it is purely a management decision, and no one can stop you from doing so.
