The first bench comprising Chief Justice Sanjay Kishan Kaul and Justice M Sundar gave the direction on a PIL by K Balu, President, Advocates Forum for Social Justice.
He alleged that liquor was sold in several liquor shops even to minors against the law.
Such a serious violation goes totally unnoticed because there was no monitoring mechanism, he said seeking installation of internet-linked CCTV cameras.
Several bars are not hygienic, he said, adding that only a CCTV-based supervision could hold persons responsible for maintaining hygiene in those places.
Balu said easy availability of liquor even to minors had been the cause of various criminal offences across Tamil Nadu.
