I personally do not know offhand but in most cases of joint and several liability, there is usually a total amount which each are responsible for, not cumulative. Thus if there are 2 people on the hook for the same issue and there is a cap, you have a better chance of recovering the full amount of the cap. This of it this way -- if there was a loan for $300 with joint and several liability, both parties are liable for the $300 but that doesn't mean you can get a windfall and recover $600. It only means that if one cannot pay or may not be responsible for the full $300, the other might be required to pay up the rest. It might be different with the ADA but I would think not.
