Case Study

Bob rented a car from Nina for a business trip to Phuket. Nina failed to deliver the car on time, causing Bob to miss a business meeting and lose a potential profit of 10,000,000 baht. Bob rented a new car from Peter at a higher cost.

Analysis

  • Nina breached the contract by failing to deliver the car on time.
  • Bob can demand specific performance, which is the delivery of the car.
  • Bob can claim damages for the additional rental cost of 5,000 baht.
  • Bob cannot claim damages for the lost profit of 10,000,000 baht because it was not a foreseeable consequence of Nina’s breach.
  • Bob can terminate the contract if Nina does not deliver the car within a reasonable time after being given notice.
