Mr. K.K. Luthra, Sr. Advocate was born in April 1925 in Khanewal (West Punjab) now in Pakistan.
In 1941, Mr. K.K. Luthra joined Forman Christian College, a renowned Institution of Lahore, where he obtained his F.Sc. and B.Sc. degrees. Thereafter, he joined Government Law College, Lahore, one of the premier institutions of law at that time. While he was studying law, , his family, which was based in West Punjab (now in Pakistan), had to migrate as refugees to Shimla, by reason of the partition of the country, where he completed his law degree in 1949 from the Government Law College, Punjab.
He was enrolled as a Pleader of the Punjab High Court in 1949 and later as an Advocate in 1954. As he was the only child of his parents who had lost every thing during the partition, his father urged him to leave the practice of law, which was a tough profession in a new part of the country, and to join the civil services instead.
At the insistence of his father he took the civil services examinations, which he cleared while immersed in the practice of law. However, he picked up sufficient number of briefs before the interview round and began to support the family. This convinced his father to let him follow his professional wish to practice as a lawyer .
He started his legal practice at Shimla, and later shifted to Delhi in 1950 where he continued to practice till his demise in 1997. Although he began his career by practicing in the area of civil law, later however he earned a reputation for himself in the field of criminal law. During his career spanning 49 years at the bar from 1949 to 1997, he regularly appeared in various High Courts as well as the Supreme Court of India in a variety of matters. However his name was always heard in the context of criminal law, which was his forte. From the early 1970s he was engaged in almost all prominent criminal cases in Delhi and often had to travel to various High Courts all over India. He was designated as a Senior Advocate of the Delhi High Court in 1984.
During his long innings at the Bar, he was lead defence counsel in numerous important cases like the Baroda Dynamite Case, the L.N. Mishra murder case, Classik Computers Case, St. Kitts Case, the Coomar Narain Espionage Case & in the post-Emergency Shah Commission of Enquiry. During the period of the Emergency (1975-77) he valiantly advised and appeared for various prominent political and social figures who were detained under MISA.
