Whether the appeal was admissible when only one of two necessary co-defendants appealed.
No. In a case against necessary co-defendants, the appeal had to be filed jointly by both co-owners; an appeal by only one lacked standing and had to be rejected.
The co-owners were necessary consorts in the underlying action. Under Article 70(2) CPC, procedural acts timely done by one consort generally benefit the others, but this exception does not apply to appeal declarations. Because B.R.________ did not join the appeal, the appellants lacked active standing in the appeal proceedings.
