Independent contractor for tort liability (agency): which statements describe exceptions where the principal may be liable?

• A. Ultra-hazardous activity
• B. Estoppel: hold-out as agent
• C. Both A and B
• D. None of the above

Answer: (C)

The key idea is that a principal normally isn’t responsible for the torts of an independent contractor, but two specific scenarios break that rule.

First, when the contractor is performing an abnormally dangerous (ultra-hazardous) activity. In this situation, the principal can be held strictly liable for injuries caused by that activity, regardless of fault or how careful the contractor was. The risk is so inherent in the activity that the person who chose to undertake it bears the responsibility for its consequences.

Second, estoppel or hold-out as agent. If the principal represents the contractor as his agent or allows that impression to be created, and a third party reasonably relies on that representation, the principal may be bound as if there were an actual agency relationship. This means liability can attach even though the contractor is technically an independent contractor, because the principal’s representations misled the other party.

So the correct approach recognizes both avenues: liability can arise from (1) ultra-hazardous activities and (2) estoppel/hold-out as agent. The choices that cover only one of these or omit one of the scenarios don’t capture the full basis for liability, whereas the option including both reflects the two recognized exceptions.
