(b) (1) In counties governed by a metropolitan government as provided for by title 7, chapters 1-3, any constable to whom a precept or process is directed by a judge or clerk of a court of general sessions may perform the constable's duties relating thereto by delivering such precept or process within a reasonable time to the sheriff of the county, who shall serve such precept or process.
(2) Upon delivering the precept or process to the sheriff as provided in this subsection (b) and taking a receipt therefor, the constable will have performed the constable's function and duty relating thereto.
