Although the decision certainly means that the D got something valuable for nothing that fact does not mean "unjust enrichment" occured. An "unjust enrichment" or quantum meruit is an equitable remedy that courts use to prevent unfairness from occuring where a D receives something of value and only by paying the P would unfairness be avoided. While it is unfair for the P here to receive nothing, this is exactly what the P agreed to do. The P allowed D to have all power to determine what they would pay, if anything. The P made a bad bargain and should have been more careful, but courts are not in the business of fixing "bad bargains." Unjust enrichment is meant to prevent unfairness, while the P may have entered a bad and unprofitable agreement, she nonetheless did so willingly and knowingly and that is not unjust enrichment because to find "unjust enrichment" here would negate the valid contract that was entered into.
