Uterios, your world seems perfect. And I believe in the real world is not; as well the world I have seen, heard and I have experienced. You acknowledged, that based on a person decision making is somehow is governed by such influences. In this regard, if a person is under influenced by something and such; why would you even considered and try to inforced the contract? Any reasonable and fair person would have been realized and took the consideration, by the fact that the individual to whom you made the contract with, was intoxicated.
You know from the beginning of the negotiation process, and knowingly know; that the person was indeed intoxicated while you made your deal. And proceed the contract anyway.
Looking at the whole picture, if anybody try to inforced such contract and making a deal with intoxicated person, knowingly and intentionally; then I find the contract was not legitimate. And therefore, the contract is none inforecible.
This because, I don't take advantage to people that are not totally themselves while making such decision.
In terms of where you take the legal class; online or in class room. Recognized Univesities or credited of something and something school. In my opinion, regardless of what education you have accomplished and what school you have attended, it make no diffence.
It's your action, behavior and your overall performance that you have represent. It is more vital; than anything else.
