That the BJP has now taken a U-turn on parliamentary tactics that it championed not so long ago should not be surprising. But, were this like a conventional U-turn, like on Aadhaar, FDI in retail, GST etc., we would remind the BJP of its stance while in opposition, call NDA2 a U-turn sarkar, have fun at their expense and move on until the next U-turn, which incidentally would be on the land bill. But, this is not an ordinary U-turn. It smacks of brazenness, contempt for dissent and disdain for institutional accountability. We must not laugh this one off. This is a serious matter.
