1. Well,there are decisions of supreme court that even if there is delay in constructions the consumer can not stop making payment of consideration money. At least this decision can go agaisnt you unless you have equity against the builder.
2. Once the court has posted the matter for delivery of judgment then it is not going to hear you under any circumstances at all.
3. Since the forum is going to pass the decision wait for sometime. If it goes against you the same can be challenged in higher forum.
4. You can cite these decisions if those are in your support. I have not gone into it and hence I can not advise on its applicability in your case.
