Facts

The appellants [A.X.] and [B.X.] founded a collective company with their brother [C.X.] on May 18, 1989, with its seat in [I.] (Canton of Basel-Landschaft). This company was registered in the commercial register on December 5, 1990. On June 17, 2011, [C.X.] terminated the company agreement as of December 31, 2011, and stated that the liquidation of the company was to be registered in the commercial register and that the liquidation was to be started immediately thereafter.

However, the Federal Court came to the conclusion that the lower court had rightly not qualified the termination letter from [C.X.] of June 17, 2011, as a registration in the sense of Art. 15 CRO, as it was a letter to the co-partners and not to the Commercial Register Office.
