There was a Supreme Court Judgement in which it was stated that the open car parking spaces cannot be sold by the
builder in their societies. I was not aware of this judgement and paid Rs. 2.5 lakhs for an open car parking in the year 2011. Now I am asking the builder to refund me this amount as as per SC judgement he cannot charge for an open car parking. The builder is saying that you had yourself purchased an open car parking so he would not return the money. What should I do? Please advise.
