What is one of the main criteria for defining an assault on a sports official?

The main criterion for defining an assault on a sports official is that it involves a physical act while the official is on duty. This is crucial because the definition of assault in this context often hinges on the official's role and the environment in which the act occurs. Sports officials are responsible for maintaining order and enforcing the rules during games or matches. When an assault occurs during this time, it not only threatens the safety of the official but also undermines the integrity of the sporting event itself.

The focus on the official being "on duty" is significant because it differentiates assaults that take place in the context of their professional responsibilities from other instances of physical altercations that may involve officials outside of their official capacity. Understanding the setting and circumstances surrounding the incident is essential for legal definitions and implications in sports law.
