These are some of the things you can do:
Approaching the Management Committee
If the member of the Housing Cooperative Society faces any problem relating to the harassment in the housing cooperative society then they can approach to the Management Committee to deal with the matters as per the Acts, Rules of the concerned State and Bye-laws of the Housing Cooperative Society.
To approach the Consumer Courts
If the management committee does not take appropriate action on the complaint of the members relating to the problems then they can approach to the consumer courts and also demand compensation by the housing cooperative society for not uses their power as per the laws.
To approach the Police Authorities
If the harassment is of serious nature then they can also approach the police authorities for taking suitable action against the offenders as per the Punitive laws and maintain dignity.
You can file a injunction suit against this harassment because there is no such provision made in co-operative society act and if its there in society bye laws with approval of AGM you can challenge its validity since bye laws wouldnt be made in a manner it prevents someone from using their own balcony as they wish unless what they’re doing is illegal.
Mental harassment claim
If things get worse and they keep harassing you then you can file a complaint against mental harassment. Mental Harassment or Emotional Abuse is any kind of non-physical attitude or behaviour that intimidates, controls, sub judicates, punishes, demeans, or isolates another person by way of humiliation, fear or degradation.
Section 294 of IPC
