The leader of the student organization argues that we must have more student participation in the administration's decision-making processes. But if her suggestion is implemented, then the next thing you know, the students will be running the school. Teachers and administrators will have no authority, and the school will no longer be a place of learning. Total chaos will ensue. We must reject the student organization's argument.
Does it commit a fallacy? Does it commit a red herring fallacy?

This has committed a RED HERRING FALLACY, because the students to be running the school and taking over the authorities of the teachers are not part of the argument, which was to involve the student in decision making of the school.

Explanation:

Red herring is a kind of fallacy that tends to the change the structure of an argument with an irrelevant topic, so as to divert the attention of the listeners from the main argument. This type of fallacy often tend to mislead listeners to make a wrong conclusion.

Involving the student in the decision making of the school is a good argument, but the red herring fallacy which is seen has tend to divert the attention of the listeners to an irrelevant topic that is not part of the argument.
