Key legal question
Whether the parties' collaboration was an agency contract, an innominate contract, or another contractual type, and whether the defendant could avoid the restrictive clause on that basis.
Extracted holding
Whatever the contractual qualification, the defendant could not escape the prohibition he had accepted; if it was an agency contract, art. 418c al. 2 CO allowed such an undertaking, and if it was innominate, contractual freedom allowed it.
Extracted reasoning
The Federal Court held that the clause was valid during the contractual relationship under either qualification. The defendant's own argument invoking arts. 340 and 340a CO was misplaced because those provisions concern post-employment non-compete clauses and, in any event, did not defeat the clause here.
