If my wish is for the genie to abide by the contract, then the thing holding him accountable is his own magic, not a human or court. The lawyers aren't there to follow the law, they're there to see that the contract is logistically sound.
If a genie cannot be beholden to his own magic, then there's really no point in expecting any kind of wish to be free of a curse anyway because he's just going to do whatever he wants regardless of what you wish for.
