Facts
- PG&E hired G.W. Thomas Drayage & Rigging Co., Inc. to remove and replace the upper metal cover of PG&E’s steam turbine.
- The contract required the contractor to perform the work at its own risk and to “indemnify” PG&E against “all loss, damage, expense and liability” resulting from “injury to property” connected with performance.
- The contractor also agreed to procure at least $50,000 in property-damage liability insurance naming PG&E as an additional insured, with coverage extended to PG&E’s property under a cross-liability clause.
- During performance, the cover fell and damaged the turbine’s exposed rotor; PG&E sought $25,144.51 in repair costs.
- PG&E dismissed its negligence claim and proceeded only on the indemnity clause, asserting it covered damage to PG&E’s own property.
- The contractor contended the indemnity clause was intended to cover only third-party property claims and offered extrinsic evidence, including admissions by PG&E’s agents and evidence of prior similar dealings.
Issues
- Whether extrinsic evidence is admissible to interpret a written indemnity clause that appears facially unambiguous.
- Whether the proper admissibility test is facial “plain meaning” or whether the language is reasonably susceptible to the meaning supported by the offered evidence.
- Whether the indemnity provision could reasonably be read as limited to third-party property damage rather than including damage to the indemnitee’s own property.
Decision
- The California Supreme Court reversed the judgment for PG&E.
- The Court held that extrinsic evidence is admissible if it is relevant to prove a meaning to which the contractual language is reasonably susceptible, even if the writing appears unambiguous on its face.
- Because the indemnity clause was reasonably susceptible to the contractor’s third-party-only interpretation, the trial court erred by excluding the proffered extrinsic evidence.
- The case was returned for further proceedings consistent with admitting and considering the extrinsic evidence on the meaning of the indemnity provision.
Legal Principles
- The admissibility of extrinsic evidence to explain a written instrument turns on whether the evidence tends to prove a meaning to which the language is reasonably susceptible, not on whether the text appears plain on first reading.
- A court must make a preliminary assessment of the proffered evidence to determine whether the asserted interpretation is one the text can reasonably bear; if so, the evidence should be admitted for consideration.
- The parol evidence rule bars extrinsic evidence used to add to, subtract from, or vary the terms of an integrated writing, but it does not bar evidence offered to interpret the meaning of the words used.
- Contract interpretation cannot rest solely on a judge’s assumed linguistic understanding; context and credible evidence of intent may be required to determine meaning.
Conclusion
The court required a contextual approach to contract interpretation: when contract language can reasonably support the meaning advanced by a party, extrinsic evidence of the parties’ intent must be admitted to interpret the writing, even if the clause seems clear when read in isolation.
