When recording Events in MINDA, you're able to update or edit them before they've been approved in the Holding Pen.
If you do notice any approved Events which have a mistake i.e. you entered the wrong animal ID, you'll need to get in touch with the LIC Customer Experience Centre. Approved Events can't be edited or deleted in MINDA but if you call 0800 264 632, the Customer Experience Centre can help you out.
