No, the signer of the licensing agreement would not be liable for any violations of the IP policy by having signed the agreement. This is because whoever signs the agreement will not be signing as an individual, but “on behalf” of their district, region or meeting, and in their capacity as the district’s chairperson, webmaster, delegate, or whichever position they hold in the district (or region or independent meeting.)
It is like when MA’s President Trustee also signs things on behalf of MA World Services in their capacity as President. They do not become personally liable for any actions taken within MA. They are signing “as MA World Services.” A corporation like MA World Services, or an entity like a MA district/region, cannot sign as the corporation or entity – an adult must sign on behalf of the corporation or entity. Likewise, anyone who signs licensing agreements granting districts, regions, or independent meetings permission to use MA’s trademarks of the MA name and logo, will be signing on behalf of, or “as” their service position for the district, region, or group that they represent, and they will not be held personally liable for any violations of MA’s IP Policy.
