Anything above that weight and the manufacturer cannot gurantee that the aircraft will maintain its structural integrity.
An overweight landing is not normally a structural issue, it is a performance issue. And it certainly isn't a structural issue with the A320.
The difference between an overweight landing or not, is that for one a maintenance inspection is performed, For every one that I have been involved with, the inspection stopped at the first check point. And some were pretty hard landings! These are pretty tough birds.
That being said though, there are performance
procedures to be followed. Starting with a landing distance calculation, and on a dry runway, it is normally not a factor. Another calculation is whether in Config FULL, a go around can be made at that weight ... on one engine!
(Some airports have second segment climb issues).
Then, brake cooling has to be calculated, and "hot brakes" must be expected.
The decision to return is ultimately the Captain's, but he would have had help in that decision. From the on-board crew and descriptions of the vibration, to maintenance and their input on possibilities. It could have been anything from flight control issues or damage on take-off, to hatches left open, to pressure seal leaks. Some are dangerous, some are not. It is always wise, when possible, to get the ship back on the ground, sort it out there.

How is an overweight landing not unsafe, though?
I can understand your concern, however, the fact that fuel dumping is not possible, and that overweight landings are certified, indicates that they will be completed safely 100% of the time. We do overweight landings often in the simulator, and other than hotter than normal brakes, I see nothing unusual.
As I said above, it is more a performance issue. For aircraft that DO
have fuel jettison capability, like the B767-300ER I fly, it is not for fear of the weight, but more to get it lighter, when possible, to keep the numbers low on landing.
Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!
