Just chanced across this report in the Mumbai Mirror, entitled about a raid done by the Weights & Measures at the Chhatrapati Shivaji International Airport in Mumbai.
I found the Delhi Dept of Weights & Measures website giving a lot of information, but can't find anything for Karnataka. Its called Department of Legal Metrology here. As usual, the govt is sleeping. If anybody can find the website for me, please drop me a comment.
