KCR announced before the elections in 2014 that TRS will make a Dalit as CM if it comes to power. But what happened after elections. We all know.
Modi in his speech at Tirupathi announced that he will give Special Status to AP if his party come to power. NDA has come to power. But now what happened we all are seeing.
We can list out many such things to say that no politician will stand on his words. So the suggestion given by you will not be implemented in India. But if this happens the voter will get a chance to question the government. Today the voter is nothing to do once he completes the voting in elections. He can't do anything expect silently protesting the unwanted happenings.

Now, suppose the government started to work on a project but couldn't complete it within the stipulated period. If it is challenged in court the government will definitely raise the issue of lack of time as defense. The main thing is the false promises that they make during election time and later forget. Well, in that case they may say they were very busy with the other projects and couldn't invest much time to the other promises, but will surely look into those promises if given another chance. If there is a debate in Parliament about this topic I'm in doubt how many will support the idea. The most interesting thing is who/which political party is going to ask for a debate on this topic? But, let's hope for the best.
