Key legal question
Whether an initial 2001 estimate of the user’s staff numbers remained binding for royalty invoices in 2002-2006 under the applicable tariffs.
Extracted holding
The initial estimate could generally remain applicable for later years if the user did not report changes; the collecting society did not need to repeat the estimation procedure annually.
Extracted reasoning
The tariff wording and the duty of orderly, economical administration allowed reliance on the first declaration for subsequent years, absent later change notices.
