No. You're assuming that your conclusion follows from your premise. That's
your logical mistake.

What about a new statute? That would clearly be A=True, yet can't be argued
that B=True - or any new statute could not create any offence.

You can't deny that.

But if my suggestion is the case, then yours must be wrong. Simply because,
as a matter of logic, you can't have a rule applying in only some cases.

You can't assume that your statement follows simply because you have reduced
it to a logical form.

To further clarify your (Tim Roberts) task in proving me wrong...

This statement:

"If it has NEVER been adjudicated that XXXXXXXX is a violation of the
law, then it is VERY LIKELY XXXXXXXX is NOT a violation of the law."

is a statement of the form "If A then B."

This means, "If A is true then B is true." This is logically
equivalent to saying either A is not true or B is true.

If this statement is FALSE then A must be true and B must be false.

Now, in the case in question:

A = "it has NEVER been adjudicated that XXXXXXXXX is a
violation of law"

B = "it is VERY LIKELY XXXXXXXX is NOT a violation of the law."

So the only way you can prove my statement FALSE is to prove BOTH of
the following:

1. It has NEVER been adjudicated that xxxxxxxxxx is a violation of
law.
2. It is NOT VERY LIKELY XXXXXXXX is NOT a violation of the law.

So far you haven't proven either of these statments.

Therefore, you cannot assert that my statement is false.
