Joseph, you can (and people HAVE been) successfully sue if an agency declares your supervision “not kosher”. It is why NY States old kosher laws had to be rewritten. If Rabbi Shirley Temple claims it is kosher and certifies it as such, you can not claim “anything certified by rabbi temple is not kosher”, since the law will not recognize one standard over another. You may say it doesnt meet standard X or something similar, but to say “not kosher”, you will lose every time. In NJ all certifying agencies must state what standards their kosher claim adheres to.
