In a big relief to former Maharashtra Chief Minister Uddhav Thackeray in the fight over control of the Shiv Sena, the Supreme Court today told the Election Commission not to decide on a plea by rival Eknath Shinde, the Maharashtra Chief Minister, to recognise his group as the real Shiv Sena. The Supreme Court is likely to take a call on Monday on whether the matter needs to be referred to a constitution bench.
