Speaking to our experts, I wonder whether a clause such as this one isn't more for businesses in general, people who have ready access to the courts and a lawyer. I feel this clause is inappropriate for the purpose of protecting the ordinary person who might be affected by a nuclear incident.
It forces people who have little knowledge, means or money to hire a lawyer not to institute proceedings because, if the claim is poorly written or poorly prepared, it will be said that it is frivolous and will be dropped. If the purpose of this clause is to protect the population as a whole, I don't think it is appropriate. You'll tell me if I'm straying very far from the truth, but it seems to me the purpose of this clause is precisely to protect businesses or, more generally, people who can gain access to the courts.
