Questione giuridica chiave
Whether the federal appeal proceedings should be discontinued after the appellant's declaration of withdrawal
Decisione estratta
The written declaration of 6 May 2007 was treated as a withdrawal declaration, which ended the dispute and justified discontinuance of the proceedings.
Motivazione estratta
A withdrawal declaration terminates the litigation; the court therefore struck the case from the docket and only had to decide costs and any party compensation.
