In Clark vs. Hackett, the Supreme Court of the United States heard a case concerning an alleged breach of contract between two parties. The plaintiff, John W. Clark, had entered into an agreement with defendant William Hacket to purchase certain goods from him at a fixed price and on credit terms. When Hacket failed to deliver the goods as promised, Clark sued for damages in a state court in New York City. The jury found that there was indeed a valid contract between the two parties and awarded damages to Clark accordingly; however, upon appeal by Hacket's attorneys it was argued that since he had not been served with notice of suit prior to trial his due process rights were violated under Article IV Section 2 Clause 1 of the Constitution (the "Full Faith and Credit" clause). In its ruling on this matter, the Supreme Court held that while service is necessary for proper jurisdiction over out-of-state defendants such as Hackett who are being sued in another state's courts - which did not occur here - it does not necessarily invalidate any judgment rendered against them if they have actual knowledge or receive sufficient constructive notice about their involvement in litigation before final judgment is issued against them by said court(s). Ultimately then, despite finding some fault with how proceedings were conducted below due to lack of service upon Hackett himself beforehand (which would have been required), ultimately upheld both findings made by lower courts regarding validity/enforceability of contract between parties involved along with award granted therein thus aff

In Clark v. Hackett, the Supreme Court was asked to decide whether a state court had jurisdiction over a case involving citizens of different states. The majority opinion held that it did not have such jurisdiction and dismissed the appeal. However, Justice Grier dissented from this decision on the grounds that Congress had given state courts concurrent jurisdiction in cases where parties were citizens of different states. He argued that since there was no federal statute explicitly denying them such authority, they should be allowed to exercise their power as granted by Congress. Furthermore, he noted that if state courts could not hear these types of cases then many disputes between individuals would remain unresolved due to lack of access or resources for litigants seeking relief in federal court. Ultimately, Justice Grier concluded his dissent by stating that allowing state courts to exercise their powers as intended by Congress would ensure justice is served and provide an avenue for resolution when other options are unavailable or inadequate
