252 P.3d 798
N.M. Ct. App.2011Background
- UNC operated five mines in New Mexico in the 1970s–80s; pollution liabilities were sought under Allstate umbrella policies; policy pollution exclusion excludes damages arising from discharges unless sudden and accidental; district court held sudden means quick/abrupt and accidental means unintended; UNC sought indemnification for environmental damages from Santa Fe Pacific Gold; Allstate moved for partial summary judgment to apply the exclusion and deny coverage; UNC appeals the district court’s interpretation and grant of summary judgment.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Is ‘sudden’ ambiguous or have a temporal meaning? | UNC argues sudden has no strict temporal connotation (ambiguous or unrelated to time). | Allstate argues sudden means quick/abrupt with a temporal component. | No ambiguity; sudden has ordinary quick/abrupt meaning. |
| Does the record show ambiguity in the term ‘sudden’ given dictionary and drafting history? | UNC asserts multiple definitions and drafting-history evidence create ambiguity. | Allstate relies on plain-meaning approach and limited extrinsic history to negate ambiguity. | Ambiguity rejected within majority view; plain meaning applied. |
| Is Allstate estopped from denying coverage based on gradual pollution? | UNC argues estoppel should bar enforcement based on industry drafting/history. | Allstate urges no regulatory estoppel based on how terms were marketed. | Estoppel not established; evidence insufficient. |
| Did the district court properly assess Allstate’s duty to defend in light of potential ambiguity? | UNC contends dismissal of duty-to-defend claim denied a fair hearing. | If allegations fall outside policy, insurer need not defend. | Duty to defend issue resolved consistent with policy scope; majority affirms dismissal on summary judgment. |
