A more thorough explanation:

Secundum subjectam materiam is a Latin term used in law. It means "according to the subject matter."

For example, if a court case is about a contract, the court will make its decision based on the terms of the contract. This is because the decision is secundum subjectam materiam, or according to the subject matter of the case.

Another example is in patent law. When evaluating a patent application, the patent office will look at the subject matter of the invention to determine if it is eligible for a patent. This is also an example of secundum subjectam materiam.

The examples illustrate how the term secundum subjectam materiam is used in law. It means that decisions or evaluations are made based on the specific subject matter of the case or application. This ensures that the decision is relevant and appropriate to the situation at hand.
