Questão jurídica principal
Whether the federal appeal against the cantonal remand decision was admissible under Art. 50 OG.
Decisão extraída
The appeal was inadmissible because a favorable ruling would not have produced a final decision; the appellate court had not made findings on a possible new contract after the building permit dispute.
Fundamentação extraída
The contested decision was an interlocutory remand decision. Although the appellants challenged the legal characterization of the contract, the Supreme Court could not finally decide all claims because the lower courts had not examined whether the parties later concluded a new agreement or modified the original one, which could ground the seller's counterclaim.
