Technician reported a Ramp/Cargo Manager cleared an aircraft for operation following a reported engine leak. The Technician reported this to Maintenance and the aircraft was directed to return to the gate for Maintenance action.

Narrative

I was assigned to a gate return for flight Aircraft X ZZZ-ZZZ1. The original Crew assigned to the push back noticed an engine leak and informed the Captain before takeoff. The Ramp/Cargo Manager went out on to the taxiway and inspected both engines before giving the flight deck the thumbs up the plane was clear for takeoff. I watched as the Manager inspected the aircraft without proper training to clear the issue regarding the leak. A Ramp/Cargo Manager went outside of his authority and OKed a plane with an engine leak and informed the Captain the plane was clear for takeoff; however the plane had orders to return to gate for a Maintenance Technician to inspect the issue. Aircraft Maintenance was immediately notified of the event. Removal of the Manager who overstepped his authority on the ramp. Understanding your assignments as a Manager and letting the proper and qualified individuals correct the issue. If safety is our most important goal; such gross violations and disregard for Passenger and Flight Crew safety must be addressed.
