Art. 11a II. Mandatory representation (1)
1 If more than 20 parties appear in a case with joint or individual submissions in order to assert the same interests, the authority may demand that they appoint one or more representatives to act on their behalf in the procedure.
2 If this demand is not complied with within a reasonable period, then the authority shall itself appoint one or more representatives.
3 The provisions on the reimbursement of the representation costs in appeal proceedings are applicable in an analogous manner to the costs of such representation. The party against whom the submissions are directed must make a payment to account towards the costs of official representation if ordered to do so by the authority.
