The partner of a San Francisco woman who was mauled to death by a 120-pound dog last month plans to file a wrongful death suit against the dogs owners, challenging the state law banning such suits by domestic partners in the process, the San Francisco Chronicle reports. California state law allows only surviving spouses, children, and parents to bring wrongful death suits. However, Sharon Smith, whose partner, Diane Alexis Whipple, was killed outside her apartment by a Presa Canario dog on January 26, plans to challenge the existing state law. I want to change some laws so that domestic partners have some recourse in the future, said Smith. As gay and lesbian couples, we cant get married. We cant file suit. Were really caught in a catch-22. Smith plans to file suit against Robert Noel and Marjorie Knoller, the owners of the dog. Noel and Knoller are under criminal investigation by police. The dog was raised through intermediaries for a prison inmate whom Noel and Knoller adopted just after Whipples death. Experts say that Smiths suit is a necessary challenge to the law. It provides an example of how vulnerable lesbian and gay relationships are, irrespective of how long-term or committed they are, said Kate Kendell, executive director of the San Franciscobased National Center for Lesbian Rights. The state cant have it both ways. You cant condition a right on marital status, then deny a whole class of people the right of access to be married. A bill introduced in December by openly lesbian assemblywoman Carole Migden would allow domestic partners to sue for wrongful death. A spokesman for Gov. Gray Davis said that the governor had not had a chance to formulate a position on the measure.
