Questão jurídica principal
Whether the appellant could access earlier mutual assistance requests before the 17 January 2001 supplement.
Decisão extraída
The earlier requests did not need to be disclosed because the later supplement contained the relevant facts and the older requests would have added nothing material.
Fundamentação extraída
The right to be heard covers access to decisive file items only. Here the 17 January 2001 supplement repeated the factual basis and specified the investigative scope, so the earlier requests were superfluous.
