Korah’s dispute with Moses is an example of a dispute with inappropriate motivation; consequently, there was no justification for it.

Any dispute for the sake of Heaven will ultimately endure, and one not for the sake of Heaven will not ultimately endure. What is a dispute that is for the sake of Heaven? These are the halakhic disputes between Hillel and Shammai and their disciples. What is one that is not for the sake of Heaven? This is the dispute of Korah and his congregation. (Mishna Avot 5:17)
