Questione giuridica chiave
Whether the appeal should be withdrawn based on the appellant's letter referring to a different filing date.
Decisione estratta
The letter could not be construed as a withdrawal of the appeal, because the appeal had been filed on 2 August 2007, not on 17 August 2007.
Motivazione estratta
The date mismatch made the stated withdrawal refer to a request rather than to the appeal itself.
