MEL 34-XX-XX-XX-B applied. ADSB out inoperative. This MEL has not been updated since the mandatory ADSB requirement that was effective in January of 2020. It is no longer applicable or usable as written. Operational notes need to be added that ensure the proper notification and approval are received from the appropriate controlling agencies prior to flight. In our case; for both flight legs we were assured that these requirements had been met. While we met the FAA requirement to operate; this MEL is still problematic. This also applies to the return flight. While we ensured that the compliance was met; there appeared to be some confusion with the requirement.Outdated MEL. MEL review to ensure compliance with FAA directives. This aircraft has flown multiple legs with this MEL applied. Our crews and maintenance control need a better understanding of the ADSB requirements. PER this MEL; the aircraft should have been grounded. It is impossible to fly in the USA and not enter ADSB airspace on any of our routes.
Air carrier First Officer reported a particular aircraft is allowed to keep flying without ADSB using an outdated MEL.
