Key legal question
Whether the sealed accounting and billing documents had to be filed in full or could be returned/partly anonymized because anonymization would be disproportionate and professional secrecy would prevail.
Extracted holding
The documents generally had to be filed, as the lower court’s blanket reliance on disproportionate anonymization and professional secrecy was untenable in the circumstances.
Extracted reasoning
The court held that the lower court relied on a summary, mainly quantitative assessment and failed to conduct the required document-specific examination. In the concrete situation, professional secrecy was largely no longer protectable, the public interest in investigating serious suspected tax offences prevailed, and the documents did not appear useless for verification of the accounts.
