It certainly points a direction to the court about the issue of spousal abuse. The actual section says “any relationship”. Because the legislation is using words to broadly describe relationships and saying “any relationship”, courts are going to very broadly construe what the term “relationship” means. When a person is being bullied by somebody else in school, that is some form of a relationship. It's obviously not a healthy one, and one that we would not want to encourage.
I think the section is fine the way it is because it sends the signal and it can be construed broadly enough to realistically encompass any type of interaction between people that will be constituted as some form of a relationship under the section.
