Legality of Election?

In New York, the condominium bylaws states that a homeowners meeting is required for election and a quorum, in the condo by-laws, it states the same and quorum is established with 2/3 of the homeowner's present. we currently have a board of managers that has decided to create a "Mail-In" election and alot of the addresses was incorrect and the ballots never received by the homeowners. Am I wrong to believe that the election is illegal and needs to be done in a "Homeowner's meeting" and quorum established? 2nd question: this is a past problem. for about 8-10 years, the board of managers was non-existent and the property management was handling the finances of the condo but in 2015, we found out that we had a 1.4 million dollar bill and a lien was established for water charges that is supposed to be included in our common charges. Can a class action lawsuit be brought due to the fact that they had a fiduciary responsibility and failed to notify the homeowners of this problem?
