A bench of justices Sanjiv Khanna and Chander Shekhar, however, permitted the traditional manufacturers of silver leaf to dispose of their existing stock of the sweet decorative which is also used in Unani and Ayurvedic medicines.
The Delhi government had issued a circular banning the use of the material made by the traditional process on the basis of a central notification to that effect.
The court passed the order after the petitioners, who were in the business of making 'chandi ka warq' by the traditional process, said they would move a representation before the Food Safety and Standards Authority of India (FSSAI) to show that their method was hygienic and without any risk of contamination.
The FSSAI, by a notification of July 15, 2016, had banned the use of the silver leaf manufactured by the traditional method, which involved the use of the intestine of a cow or buffalo, saying it was unhygienic and there was a risk of infection and contamination of the silver leaf.
The FSSAI had also told the court that there was a new method of manufacturing 'chandi ka warq' that involved beating sheets of black specially treated paper and polyester sheets coated with food-grade calcium powder.
The petitioners had, on the other hand, contended that their method was not unhygienic as the animal skin was dried and processed to make it hygienic.
While asking the petitioners to make a representation before the FSSAI, the bench expressed hope that the authority would take a decision and communicate it within three months of receiving the representation.
