Questão jurídica principal
Whether the cantonal appeal authority violated the right to be heard by warning of reformatio in pejus and by reducing the flat deduction to 20%.
Decisão extraída
No violation of the right to be heard occurred; the warning clearly indicated the intended worsening and the reasons, and the decision was sufficiently reasoned.
Fundamentação extraída
The letter of 28 October 2002 specified the proposed reduction and the need to prove actual expenses. The decision itself stated that no documents justified expenses above 20%.
