Appellants contend that the Court of Appeals erred in denying the writ of mandamus, in that the Director of Finance has a mandatory legal duty to deduct CARE membership dues from the wages of its members who have requested such a deduction. This duty is claimed to arise from the provisions of Cleveland City Ordinance No. 421-60, which provides, in pertinent part, as follows:

“Be it ordained by the Council of the City of Cleveland:

“Section 1. That pursuant to the authority of Section 1321.321 Revised Code, the Director of Finance is hereby authorized to deduct from the salary or wages of any city employee who belongs to a labor union, the monthly dues of such labor union as the city employee voluntarily subscribes to in a written authorizationfiled with said Director of Finance requesting such deductions. ”* (Emphasis added.)

Assuming, arguendo, that this ordinance was intended to impose a mandatory duty upon the Director of Finance, it is clear that no duty arises until an employee files a written authorization with the director. The stipulations do not indicate that the members of CARE have filed such an authorization with Director Medvick. For this reason, we hold that appellants have not proved the existence of a clear legal dirty, and are not entitled to the issuance of a writ of mandamus. State, ex rel. Pressley, v. Indus. Comm. (1967), 11 Ohio St. 2d 141.

The judgment of the Court of Appeals is hereby affirmed.

Judgment affirmed.
