An Indian court Tuesday upheld a ban on wearing hijab in class in the southern state of Karnataka, saying the Muslim headscarf is not an essential religious practice of Islam in a ruling that is likely to further deepen religious tensions in the country. The high court in Karnataka state delivered the verdict after considering petitions filed by Muslim students challenging a government ban on hijabs that some schools and colleges have implemented in the last two months. The ban does not extend to other Indian states, but the court ruling could set a precedent for the rest of the country.

That led to counterprotests by Hindu students wearing saffron shawls, a color closely associated with that religion and favored by Hindu nationalists. More schools in the state followed with similar bans and the state’s top court disallowed students from wearing hijab and any religious clothing pending a verdict. The court in its ruling said the state government had the power to prescribe uniform guidelines for students as a “reasonable restriction on fundamental rights.”
