No unauthorised chemicals should be used in the fireworks and the sound level should not exceed 125 decibel, a division bench comprising Justices Thottathil B Radhakrishnan and Justice Anu Sivaraman said in the order.
The bench was hearing a plea by the private Paramekkavu and Thirvambadi Devaswoms, which fund the annual Pooram festival in the premises of the famous Vadakkunnathan Temple in Thrissur, for permission to hold fireworks display. The festival is currently on and will culminate on Apr 18.
