Quite correct.
However
for instance to protect inexperienced players in events arranged for their training.

which is a strong indication that this was the case here, in which case RA has not exceeded its power.
Which part of 40B2a are the RA relying on?
(i) is empowered without restriction to allow, disallow, or allow conditionally, any special partnership understanding.
A psych by definition is not a special partnership understanding.
(ii) may prescribe a System Card, with or without supplementary sheets, for the prior listing of a partnership’s understandings, and regulate its use.
You may regulate the use of the System CArd - but the psych does not appear on the system card and thus cannot be regulated.
(iii) may prescribe alerting procedures and/or other methods of disclosure of a partnership’s methods.
Doesn't apply here (if the bid by South was a psych)
(iv) may disallow prior agreement by a partnership to vary its understandings during the auction or play following an irregularity committed by the opponents.
No irregularity applies in this situation.
(v) may restrict the use of psychic artificial calls.
The 2D call (if a natural psych) is not artificial.
Note that the TD is to presume misexplanation rather than mis-bid in absence of evidence to the contrary. The evidence is usually a system card or partnership notes. Were any available?
No matter how well you know the laws, there is always something that you'll forget. That is why we have a book.
Get the facts. No matter what people say, get the facts from both sides BEFORE you make a ruling or leave the table.
Remember - just because a TD is called for one possible infraction, it does not mean that there are no others.
In a judgement case - always refer to other TDs and discuss the situation until they agree your decision is correct.
The hardest rulings are inevitably as a result of failure of being called at the correct time. ALWAYS penalize both sides if this happens.

Under current law, IMO, the TD should...
1. Establish the actual NS agreement. With no evidence to the contrary, the TD might well believe South, In which case, North should have alerted.
2. Determine whether EW were damaged. The TD is likely to judge that EW would have fared better with correct information.
3. Judge whether subsequent EW passivity is wild and gambling -- or a serious error unrelated to the infraction. A TD familiar, with the law, should judge that East's timidity does not qualify as such.
4. Estimate and weight likely outcomes, assuming EW have correct information, North remains in ignorance, and his failure to alert is UI to South,
e.g. 3N+1 or +2 , 5♦=, ♦ partscores, and the actual result.
5. As well as players at the table, the TD should check his assessments with their peers and other directors. The TD should probably assign most weight to 3N+2, giving the victims the benefit of the doubt. If the TD strongly suspects North of prevarication, he might record the incident, with a view to further sanctions.
6. Study of events at other tables might help the TD to estimate likely results, objectively. Unfortunately, this sensible procedure is deprecated by legal experts, for reasons that aren't obvious.
