'The lifting of the ban by the division bench of the High Court is unfortunate. We will seek opinion from the state advocate general and other legal experts and will certainly go in for an appeal,' Achuthanandan told reporters in Kannur.
The multinational companies Coca-Cola and Pepsico had in separate petitions on Aug 18 challenged the order banning their aerated drinks on the ground that state government's action was unconstitutional.
After hearing the arguments of all concerned, the bench consisting of Chief Justice V.K. Bali and Justice M. Ramachandran said that the state had no right to ban the products.
'This decision can be taken only by the Central government and the state government has no right. The orders of the state government banning the products were harsh, unreasonable and taken hurriedly,' said the bench.
It also noted that the cola companies had not got social justice.
The Kerala government had on Aug 9 banned the manufacture and sale of the soft drinks Pepsi and Coke in the state after tests by the New Delhi-based Centre for Science and Environment showed high quantities of pesticides in 12 branded samples.
In their petitions, the cola giants pointed out that their products were safe and no scientific studies had shown any harmful contents. Both Pepsi and Coke have bottling plants in Palakkad district.
