According to A.G. v P.Y.A. Quarries, who can sue for public nuisance?

In the case of A.G. v P.Y.A. Quarries, the court established that any member of the affected class can bring a claim for public nuisance. This means that individuals who are part of a group that is harmed or affected by the nuisance have the standing to sue. The rationale is based on the idea that public nuisances impact a particular community or group of people, rather than just a single individual. Therefore, if a substantial number of people in a specific area are adversely affected by a defendant's actions, those individuals collectively can initiate a legal action.

Other options like local government officials, neighbors only, or state representatives do have roles in dealing with public nuisances but do not encompass the broader category of all affected individuals allowed to bring suit. Local government officials may act on behalf of the community, and state representatives can address public interests, but ultimately it is the affected class members themselves who have direct standing to sue based on the precedent set in this case.
