Actually it can be both. Unlike in the real world of physics, the unreal world of the Internet has morphed perceptions. And since in the real world dualities cannot exist, this must be quantified. Which is the reason the engine should not just check if the certificate is valid, but should also check if it is invalid. If so, it must then be rejected.
