Issuance of Share Certificate in my Society in Mumbai

Hello, I am hoping you could help with my query regarding the issuing of members share certificate. Background : - I and some other people had purchased flats in Mumbai (directly from the builder) prior to the formation of the Housing Society - The housing society was formed and has taken over the management of the building and begun issuing the share certificates to members. - The builder had collected the property tax from some members and failed to deposit this with the BMC. The BMC has raised this demand on the flat owners for this amount. This is documented. - We have filed a case in Mumbai high court and it has been admitted. We have informed the BMC of this matter and requested them to collect the outstanding from the builder. - Meanwhile the society is demanding that we pay BMC before they issue the share certificate to us. The case in court may take years to get resolved. - There is no other outstanding toward the maintenance or any other charges to the society. My question is as follows: Is the Society legally entitled to withhold the share certificates because the BMC demand? If not, what action can we take to get the share certificates issued to us? Thanking you in advance
