That depends. OP does not mention his jurisdiction, but in the ACBL it is not permitted to psyche artificial bids. Perhaps there is such a rule in other places as well.
Not quite.
Quote
ACBL General Convention Chart, Item 2 under "Disallowed": Psyching of artificial or conventional opening bids and/or conventional responses thereto. Psyching conventional suit responses, which are less than 2NT, to natural openings.
It looks to me like the 2NT call in question was an overcall, not an opening bid, so the prohibition does not apply. I also suspect it happened online.
Added: Oops, I see this was already caught. Sorry. Gigi, please be aware that partnership agreements as to the meanings of bids are not promises to opponents. If the explanation of 2NT was correct, there has been no infraction of law, even if the player systemically had another call which might have better described his hand.
