The reports you filed were then collated at Herdon and filed under one LM-2 report. It's one of the largest reports filed by any labor organization. But I can tell you that your MEC is not recognized as the bargaining agent. Your MEC chair cannot sign a contract with the company without the President of ALPA signing.
If you are sued by the company or by a member it is ALPA national that is the defendant. ALPA gives you as much autonomy as it can but the Department of Labor does not recognize your MEC as a local.
