I guess the last one is really a bit of a trick. For those of you flying aircraft with 'artificially' lowered MLW: What would you do if you had to land above your stated MLW but below the aircraft's actual design MLW. Would you follow the overweight landing checklist? I'm sure you would log the event, just to satisfy formalities.
Assuming "had to land" means an emergency or abnormal operations then exactly as you say. Assuming a normal landing, the only outcome will be paperwork.
