That's not how it works. What your opinion is or even your lawyer's opinion is just an opinion. Ultimately someone can bring a case in a court and it's decided then. You can advance your legal theory as to why it is allowed, and it may be a sufficient defense, or it may not. There is no a priori certainty in these things... the closest you might get is precedent.
The jocular saying is that, in England, "everything which is not forbidden is allowed", while, in Germany, the opposite applies, so "everything which is not allowed is forbidden". This may be extended to France — "everything is allowed even if it is forbidden" — and Russia where "everything is forbidden, even that which is expressly allowed". While in North Korea it is said that "everything that is not forbidden is compulsory"
