In the case of Zeier v. Zimmer, Inc., 2006 Ok. 98 (12/19/06), the Oklahoma Supreme Court has held that a medical malpractice affidavit pleading requirement similar to the one adopted in Georgia violates a "special law" provision of the Oklahoma constitution similar to a provision of the Georgia constitution. The Oklahoma case is summarized by John Day in his great blog.
the Oklahoma Constitution that provides that ""The Legislature shall not except as otherwise provided in this Constitution, pass any local or special law … Regulating the practice or jurisdiction of, or changing the rules of evidence in judicial proceedings or inquiry before the courts." Similarly, the Georgia Constitution, Art. 3, § 6, ¶ IV, provides in part as follows: " Laws of a general nature shall have uniform operation throughout this state and no local or special law shall be enacted in any case for which provision has been made by an existing general law, . . . No special law relating to the rights or status of private persons shall be enacted."
