Is there any procedure how founders of an LLC can appeal a guarantee agreement signed by the chairman of the board? The founders believe that it was impossible to sign such an agreement, that it significantly worsens the financial condition of the enterprise, that the chairman of the board did not have the right to sign such an agreement without discussion with the founders. Details: the agreement was signed in 2008 without the participation of a notary, there was no information about it at the enterprise, not indicated in the annual report.
