Whether the inadmissibility order of 26 June 2010 should be set aside because the advance on costs had been paid in time.
Yes. The payment was received by the court registry on 17 June 2010, thus in time, and the earlier order resulted from a manifest omission.
Under Art. 472a CPC, the chamber may annul an inadmissibility order in case of manifest error or omission; the overlooked payment justified revocation and continuation of the appeal proceedings.
