962 N.W.2d 71
Iowa2021Background
- Mt. Crescent contracted Challenge Quest to design/build a 1576-foot zip line in 2014; Challenge Quest provided four days of site-specific operator training and then turned operations over to Mt. Crescent.
- Mt. Crescent later hired Sky Line (without notifying Challenge Quest) to replace the original rope-pulley braking system with a Sky Line “zipSTOP” magnetic-resistance braking system in July 2016.
- The zipSTOP system required an operator to manually redeploy the brake block before it would function; an operator failed to redeploy after the previous rider, and Lukken struck a wooden pole while traveling the line in October 2016, fracturing his neck.
- Before riding Lukken signed a broad release/waiver that expressly disclaimed liability for “any and all negligence” by Mt. Crescent and related parties.
- The district court granted summary judgment for Challenge Quest (no duty/causation because the original braking system had been replaced) and for Mt. Crescent (waiver barred negligence claims). The Iowa Supreme Court affirmed Challenge Quest’s dismissal but reversed as to Mt. Crescent to permit claims alleging willful, wanton, or reckless conduct.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| 1. Did Challenge Quest owe a duty to Lukken after it completed work and Mt. Crescent replaced the braking system? | Lukken: Challenge Quest retained duties to design, instruct, and warn that extended to riders despite later changes. | Challenge Quest: Control and responsibility transferred to Mt. Crescent; replacement braking system cut off duty. | Held: No duty as a matter of law once Challenge Quest’s braking system was removed and control transferred; summary judgment affirmed. |
| 2. Can Challenge Quest be liable for a design/product defect when a different braking system later caused the injury? | Lukken: Original design produced excessive speeds that left brakes inadequate, so Challenge Quest’s design contributed to risk. | Challenge Quest: The injuring product was Sky Line’s zipSTOP, not Challenge Quest’s product; causation severed by replacement. | Held: Causation fails; plaintiff must show defendant manufactured/supplied the product causing injury—Challenge Quest’s product was no longer in place. |
| 3. Does Lukken’s pre-ride waiver bar negligence claims against Mt. Crescent? | Lukken: Waiver language may be broad but should not shield grossly culpable conduct; waiver ambiguous as to extreme misconduct. | Mt. Crescent: Waiver is clear and unequivocal, releasing “any and all negligence,” and is enforceable under Iowa law. | Held: Waiver bars ordinary negligence claims (enforceable as clear and unequivocal). |
| 4. Is the waiver enforceable to bar claims of willful, wanton, or reckless conduct (gross negligence/wantonness)? | Lukken: Public policy prohibits exculpation for wanton/reckless/grossly culpable conduct—waivers should not bar those claims. | Mt. Crescent: Waiver language purports to waive all negligence; district court said it covered gross negligence. | Held: Exculpatory clauses are unenforceable to the extent they attempt to eliminate liability for willful, wanton, or reckless conduct; summary judgment reversed as to those claims and case remanded. |
