You will not have any luck enforcing that court judgment if the recipient does not want to play ball. All they need to do is transfer the money to another country.
It is very unlikely that law enforcement would help you in a situation like this, especially internationally.
Very unlikely, the checksum would prevent that.
And most banks (even though I’m unsure it is mandatory) will check the recipient, if totally mismatched a warning will be raised.
But if you send money to the wrong iban+recipient, the money is gone.
