Gerret Schimmelpennick and Adrian Toe Laer, trading under the firm of R. and J.R. Van Staphorst v Josiah and Philip Turner was a case heard by the United States Supreme Court in 1832 that dealt with an issue of contract law between two parties from different states. The dispute arose when Gerret Schimmelpennick and Adrian Toe Laer, who were merchants based in New York City, entered into a contract with Josiah and Philip Turner to purchase goods for resale at their store located in Pennsylvania. When the Turners failed to deliver on their promise as outlined in the contract, Schimmelpennick & Co sued them for breach of agreement before a court located within Pennsylvania's jurisdiction where they won damages amounting to $2,000 plus interest costs incurred due to non-delivery of goods as agreed upon initially by both parties involved. The Turners appealed this decision all the way up to US Supreme Court which ultimately upheld it thereby affirming that contracts made across state lines are legally binding regardless of whether or not one party is domiciled outside its own state’s borders at time such agreements are formed or executed subsequently thereafter

In Gerret Schimmelpennick and Adrian Toe Laer, Trading under the Firm of R. and J. R. Van Staphorst v Josiah and Philip Turner, Justice McLean delivered a dissenting opinion in which he argued that the Court should not have dismissed the case on procedural grounds because it was brought to court by an agent acting on behalf of two individuals who were citizens of different states than those involved in the dispute (New York vs New Jersey). He further argued that since this was a contract dispute between parties from different states, it fell within federal jurisdiction as outlined by Article III Section 2 Clause 1 of The Constitution. Therefore, Justice McLean concluded that dismissal without hearing any evidence or argument presented by either party would be unjustified given its potential implications for interstate commerce disputes going forward.
