What is “material and substantial disruption?”

The Act says that “material and substantial disruption” means “any conduct that intentionally and significantly hinders another person’s or group’s expressive rights.” The Act also says that “material and substantial disruption” does NOT include “conduct that is protected under the First Amendment” including such First Amendment conduct as “lawful protests and counterprotests in the outdoor areas of campus or minor, brief, or fleeting nonviolent disruptions that are isolated or brief in duration.” We believe that this definition, in less legal terms, says that material and substantial disruption means that the expressive rights of another are so interfered with that they effectively cannot exercise their rights to engage in expressive activities. What is clear is that a peaceful counterprotest is not materially and substantially disruptive unless it makes it unreasonable for a speaker to try to continue their expressive activity.
