Court of Appeals of Texas January 27, 2000, No. 09-99-197 CV (In the Interest of A.D.)

OPINION

DAVID FARRIS, Justice (Assigned).

This case turns on one underlying issue: does the authority under Tex. Fam.Code *467Ann. § 158.502 (Vernon Supp.2000) to grant an administrative writ of withholding “at any time” violate the prohibition against retroactive laws, see Tex. Const. art. I, § 16, if it is applied to a time barred child support obligation?
