Practice question: Mistake of Law as Basis for Solutio Indebiti

Multiple Choice Hard

Practice question

A lessee’s written contract limits lawful escalation. The lessor breaches those terms and receives excess rent. A court rejects the lessee’s asserted mistaken-law basis but finds a contractual refund obligation. The lessor insists that Article 2155 rejection makes the refund claim impossible. Resolve under Domestic Petroleum.
  1. The contractual basis may support recovery independently of solutio indebiti
  2. Every rejected quasi-contract theory eliminates contractual rights
  3. Only Article 2155 can ever support a refund
  4. The lessor’s breach becomes lawful automatically
  5. All contract terms disappear when money is paid
