Inbound aircraft had Green SYS LO PR event on ECAM (Electronic Centralized Aircraft Monitor) on arrival. Inbound Captain told me the Green SYS HYD pressure went to zero. There were multiple previous discrepancies for green sys lo pressure and other green sys discrepancies. MX (Maintenance) took the aircraft and [Maintenance Control] told me parts were on the way from ZZZ to fix the problem. Shortly after; I was informed that the aircraft had been returned to service with MEL 29-12-F ECAM Warnings and Cautions for Eng Pump LO PRESS. I called [Maintenance Control] and inquired about the MEL. He told me that ZZZ1 MX did not like working on Airbus A/C and put the MEL on before consulting [Maintenance Control]. With many previous discrepancies; I did not feel that the MEL was appropriate for the current status of the aircraft. The aircraft was in a MX base.There seemed to be a lack of communication between the ZZZ1 MX base and [Maintenance Control].Better communication among all that were involved would have had a better potential outcome.
Captain reported concerns when an aircraft with multiple repeat write ups of the Green Hydraulic system were not repaired at a maintenance base. Instead; maintenance elected to defer the green system hydraulic pumps.
