Service of notice of six-month review hearing to a Mexican resident by first class mail is sufficient. Appellant father, a resident of Mexico, appealed the order terminating his reunification services at the six month review hearing. He contended that service of notice of the hearing was governed by the Hague Convention, which required service by registered mail. The appellate court rejected the argument, finding that the Hague Convention requirements do not apply to service of notice of review hearings. The Legislature has determined that notice by first class mail is sufficient, and here the notice complied with California law.
