The Interstate Commerce Clause, also known as the Commerce Clause, is a provision that is incorporated in the Constitution of the United States under Article 1, Section 8 and Clause 3. The clause stipulates that the United States Congress be empowered to regulate commerce with respect to foreign nations, among the several states and with the Indian Tribes (Gordon 2014).
Under Article 1 section 8 and Clause 3 of the US Constitution, the Federal Government can regulate his farm and business. The Commerce clause is applicable for all commerce and trade that takes place between the states of the United States. Under the clause it could be argued that the growing and selling of the farmer’s products and activities affect the interstate commerce, therefore, it is subject to the regulation of the Federal Government (Voigt 2015).
In his defense, he does not much of an argument against the government but he may refer to the case Wickard v Filburn  317 U.S. 111, where it was held by the court that an individual farmer who intended to use his wheat products for personal consumption, was subject to the Federal Government regulation. Jim may argue that his activities and its effects are local and it does not affect interstate commerce, whereas the clause regulates trade and commerce among the several states of the US.
However, owing to the economic nature of the activities, it would have an effect on the interstate commerce despite the local character of the activities. Hence, there is a probability that the the court would not favor Jim’s argument.
