(1) No person may, without reasonable excuse, enter or remain within a relevant place without wearing a face covering.
Regulation 4 states:

I am particularly interested in how 'severe distress' is defined. Is this a legal definition? How is 'severe' determined, and how would a court decide if a person's distress was 'severe' enough? Is there any legal test to establish a threshold for this?
Have there been any cases in England/Wales/Scotland where this has been tested - if so, how would I go about finding information (as somebody who is interested in law, but has no legal training or background)?
