- The master of a ship commissioned salvors from Europe to save his ship, which was sinking in an Argentinian river
- Was the master authorised to conclude salvage contracts on behalf cargo owners out of necessity?

- Agents may make contracts out of necessity if it can be stablished that it was a true necessity
- The agent (master) should have utilised local salvors who had knowledge of the local river
