Questão jurídica principal
Whether the seller lost the right to rescind the instalment sale contracts after demanding the remaining purchase price and initiating debt collection.
Decisão extraída
Demanding the outstanding price and commencing debt collection did not forfeit the seller's later right to rescind after a further notice period.
Fundamentação extraída
Art. 226h OR does not create an irrevocable election comparable to warranty remedies in a work contract; the price claim is a mere accessory to the claim and does not extinguish the rescission right. This also fits the purpose of the retention-of-title arrangement.
