Questione giuridica chiave
Whether the appeal against the incidental decision in case 2C_234/2011 was admissible under Art. 93 LTF.
Decisione estratta
No; the appellant showed neither irreparable legal prejudice nor that an immediate final decision would avoid a long and costly evidentiary procedure.
Motivazione estratta
Even if the respondents were denied party status, the TAF case would continue against Swissmedic, so no final decision would result.
