Nicholls v. Webb was a Supreme Court case in which the plaintiff, Nicholls, argued that he had been wrongfully denied his right to vote in an election for members of Congress due to a law passed by the state of Georgia. The defendant, Webb, argued that the law was constitutional and should be upheld. The court ultimately ruled in favor of Nicholls and declared that states could not pass laws denying citizens their right to vote based on race or color without violating the Constitution's guarantee of equal protection under the law. This ruling established an important precedent protecting voting rights from racial discrimination and laid down foundational principles for civil rights legislation still used today.

In this case, the plaintiff in error argued that a contract between himself and the defendant was void because it had been made without consideration. The Supreme Court disagreed with this argument, holding that an agreement to pay for services rendered is valid even if there is no other consideration given. Furthermore, they held that when one party has already performed their part of the bargain and received nothing in return from the other party, then they are entitled to recover damages equal to what would have been due under normal circumstances. In conclusion, although contracts must be supported by some form of consideration in order for them to be enforceable at law or equity, agreements which involve payment for services rendered can still be enforced even if no additional considerations were provided.
