Questão jurídica principal
Whether the seized documents, including correspondence with the tax authority, had to be returned rather than disclosed after the sealing request.
Decisão extraída
The correspondence already in the tax authority's possession did not need to be produced and could be returned; the appeal failed on that point.
Fundamentação extraída
The court accepted the lower court's view that the authority already possessed its own correspondence, so production of those papers was unnecessary and no legal error was shown.
