Dehradun: In a major blow to the BJP-led central government, the Uttarakhand High Court on Thursday set aside President's Rule in the state, restoring Congress leader Harish Rawat as the chief minister, nearly a month after he was ousted. The dramatic decision, also asking Rawat to prove his legislative majority in the 70-member assembly on April 29, triggered Congress celebrations while the Aam Aadmi Party (AAP) called it a "huge embarrassment" for the Narendra Modi government. The court came down heavily on the central government for its March 27 move to dismiss Rawat under the much contested Article 356 that empowers the union cabinet to impose President's Rule in a state. The case "brings to the fore a situation where 356 has been used contrary to the law", the court said, adding the article should only be used as a last resort. "The proclamation of March 27 stands quashed," said the court in the "status quo ante" order, meaning the previously existing state of affairs was being restored. A visibly pleased Rawat hailed the decision as "a victory for the people". "Uttarakhand has got justice. I stand vindicated," he told the media shortly after the verdict. Uttarakhand was plunged into political uncertainty after nine Congress legislators, including former chief minister Vijay Bahuguna, whom Rawat replaced, revolted and turned to the Bharatiya Janata Party (BJP). The crisis peaked on March 18 when the assembly passed the budget Appropriation Bill by voice vote even as the opposition, including the rebel Congress members, sought recorded voting. But Speaker Govind Kunjwal declined the request, leading the BJP to cry foul. Rawat was then asked by Governor K.K. Paul to prove his majority on March 28. Just a day before, the central government ousted the Rawat-led government by imposing President's Rule. Rawat immediately went to court. On Thursday, Rawat said the ruling to restore his government had begun a "new phase" in the state and asked the Modi government to honour its stated policy of "cooperative federalism". The BJP claimed the court ruling was not a surprise. Its general secretary and Uttarakhand affairs in charge Kailash Vijayvargiya, who played a key role in the developments leading to Rawat's ouster, insisted that Rawat won't be able to prove his majority. "We will prove on April 29 that (the Rawat government) was and is in minority," he said in New Delhi. After ouster of Rawat, Vijayvargiya had claimed that Congress-led governments in Himachal Pradesh and Manipur were on their way out -- like it happened earlier in Arunachal Pradesh. But another senior BJP leader, Subramanian Swamy, slammed Attorney General Mukul Rohatgi and Solicitor General Ranjit Kumar for the fiasco. "Time to get a new AG and SG for the BJP government... We can win the Uttarakhand case," Swamy tweeted. BJP sources said the central government was considering moving the Supreme Court. An overjoyed Congress called the court ruling a victory for democracy and the judicial system "to whom alone aggrieved citizens can turn for relief". "The imposition of President's Rule was unconstitutional," spokesman Abishek Singhvi said in New Delhi. "The law was deliberately and consciously violated by the central government. We hope that those who are watching different states with greedy eyes should learn a lesson." Delhi Chief Minister Arvind Kejriwal said the court verdict was "a huge embarrassment to the Modi government". "Till now the Modi government used to declare our orders null and void. Today, the high court has declared their order null and void."
