Published Decisions


ACS Systems, Inc. v. St. Paul Fire & Marine Ins. Co., (2007) 147 Cal.App.4th: Successfully defended St. Paul in a case where the Court held that an Insured’s unsolicited fax transmissions of ads did not trigger insurer’s duty to defend under the advertising injury offense “making known to any person or organization written or spoken material that violates an individual’s right of privacy.”  The coverage applied to liability for injury caused by the disclosure of private content to a third party (invasion of secrecy privacy), not to injury caused by receipt of the unsolicited fax (invasion of solitude privacy).  There was no coverage for “property damage” caused by an “accident” because, even assuming the former, there was no “accident” where the insured intended the fax transmissions to occur.

St. Paul Mercury Insurance Co. v. Frontier Pacific Insurance Co., (2003) 111 Cal.App.4th 1234: Ms. Boyd represented St. Paul in obtaining a decision that an additional insured has no reasonable expectation of coverage for its own negligence or strict products liability when its contract with the named insured requires indemnity and insurance coverage only for liability caused by the named insured.  Further, a standard 2010 additional insured endorsement providing coverage for liability arising out of the named insured's ongoing operations for the additional insured does not cover liability arising out of defects in equipment leased from the additional insured but used in operations for a third party.  Where the indemnity and insurance provisions of the contract depend upon the named insured's liability for the claimed injuries, allocation of a settlement among insurers may require apportionment of fault in addition to equitable principles.

Hooker v. Department of Transportation, (2002) 27 Cal.4th 198:  Represented CalTrans in a case where the California Supreme Court held that a hirer of an independent contractor is not liable to an employee of that contractor merely because the hirer retained control over safety conditions at a work site.  Liability may only be imposed where the hirer's negligent exercise of retained control affirmatively contributes to the employee's injuries.  Mere evidence that a hirer is aware of an unsafe practice and fails to correct it is insufficient to raise a triable issue of fact that the hirer's exercise of retained control over safety issues affirmatively contributed to the employee's injuries, or even to the adoption of that unsafe practice by the employee.

Globe Indemnity Company v. Superior Court, (1992) 6 Cal.App.4th 725: Held the insurer has a right to require the insured to submit to an examination under oath concerning all proper subjects of inquiry and cannot act in bad faith by withholding payments, no matter how long it takes for insurer to process the claim.
