Although the Act does not prohibit oral requests, a request must be in writing before § 552.301 applies. Under that section, a governmental body that receives a written request for information it considers exempt from disclosure (even though there has been no specific previous determination that such information is exempt) must ask for a decision from the Attorney General within 10 days of receiving the written request. § 552.301(a) and (b). Oral requests do not trigger this 10-day deadline. See Tex. Att'y Gen. ORD-304 (1982).
