In State ex rel. Kriedeman v. Upham (1927) 116 Ohio St. 606, 157 N.E. 20, Kriedman filed a mandamus action to compel the state medical board to issue him a certificate for the limited practice of medicine and surgery as chiropractics, under Section 1274-2, of the General Code, which provided: Any person, practicing in Ohio who at the time of the passage of this act shall actually be engaged in this state for a period of five years continuously prior to October first, 1915, in the practice of any one or more of the limited branches of medicine or surgery hereinbefore enumerated, and who shall present to and file with the state medical board an affidavit to that effect after the passage of this act shall be exempted from the examination, and shall be entitled to receive from said board a license to practice, upon the payment to said board of a fee of twenty-five dollars. The examination of all other applicants shall be conducted under rules prescribed by the board and at such times and places as the board may determine. The court affirmed the decision of this court, which denied the writ, because Kriedman did not have the "continuous practice" necessary to entitle him to a certificate without examination. While Kriedman had, in fact, practiced chiropractic medicine during the five years immediately preceding the effective date of the statute, he did not have many patients, and during that same time period, also worked as a motorman and part-time conductor on a street railway. Despite the fact the statute did not define "continuously," the court found "it would be absurd to claim that treatment of a very few patients during a period of five years would constitute a continuous practice during that period." Id. at 608.
