An unconscionable contract is a contract which is drafted in such a manner that it favors one party and is unfair and harsh on the other party, it gives a higher bargaining power to one party over the other. Such contracts should not be enforceable as they give a greater advantage to one party over the other.
Such a contract may be drafted by taking an advantage of the mental condition, age, capacity to enter into a contract, the knowledge about the subject, etc. by one party of the other. The courts step in, in case of such contracts and modify the same when at a later date the circumstances make the contract completely one sided making it irrelevant.
When one party takes an unconscionable advantage of the other, the act may be considered to be a criminal fraud or a civil deceit.
For example: Where one expert dealer enters into a contract with a customer, who does not have a lot of knowledge about that subject, the contract entered may be an unconscionable one and therefore the court can intervene here and modify the contract.
The offering, giving or receiving anything of value which influences the action of an individual while discharging his/her duties is called giving bribe.
