Narrative:

Xyz flight YYY, xx, aircraft xaxa, ZZZ-AAA-BBB returned to the gate at ZZZ after taxi out due to a left VHF problem. Per xyz MEL it is acceptable to dispatch with an inoperative left VHF unlike abc airline's procedures (my employer). I suggest with the left VHF inoperative there should be no dispatch since the left VHF is off the dc standby bus.

PER XYZ MEL IT IS ACCEPTABLE TO DISPATCH WITH AN INOP L VHF UNLIKE ABC AIRLINE'S PROCS (MY EMPLOYER).
