Justice Sanjiv Khanna, who took oath as the 51st Chief Justice of the country today, is on the trail of his "missing" ancestral home in Amritsar. The pre-Independence era house was built by his grandfather, Sarav Dayal. Sources close to Chief Justice Khanna revealed that whenever he visits Amritsar, he visits Katra Sher Singh. The stop-over is a pilgrimage of sorts. With time, the area has changed, but Justice Khanna still tries to find the house built by his grandfather.
