Associate Member Application

We have a situation in our society. The MC term was over last year 2018, election were due, but they did not conduct election as per procedure and during the AGM 2018 had election by calling if anyone wants to join MC. Two new members gave their name and the existing 4 members re-elected themselves for the position. After that they made situations such that the new members could not attend the first MC meeting, as they used to announce on the days when the new members were not available. After that they without the new members, they continued to be in the MC and hold office bearers position. They are 4 members in the MC which are holding positions for last 5yrs. And Secretary for last 10years. Our society consist of 21 flats and 9 commercial. Now members have objected and called for registrar letter for them to have re election. They only stated they have resign but have not given their resignation. Secondly there are 3 members who have got their Associate Membership application filled, can they give to this MC, can they sanction their application. As these 3 members would like to contest for the forthcoming election in September 2019? What can be done, as members do not want these 4 existing MC to nominate themselves again for election, as members are disappointed with their performance and arrogant behavior more like dictatorship? What is the solution for these 3 associate members to contest in the election? What should be the strength of the MC for the society like ours?
