xiv. In fact on the date of his retirement, (Late) Justice Shri.V R Krishna Iyer, Former Supreme Court Judge and acclaimed jurist of international repute wrote thus:
"To honour the great Chief Justice Bannurmath, the Chief Justice of Kerala, I join you to pay homage to that high noble functionary. He was a great judge and the qualities of a good justice in the words of Socrates run thus: four things belonged to judge; to hear courteously, to answer wisely, to consider soberly and to decide impartially'.
His departure leaves a void in the judiciary of Kerala, because it is difficult to find a man of his humility, erudition, compassion and gentlemanliness. He is too young to retire as his rich services are needed for the country at a time when judiciary is normally losing its sublime stature. Our nation is glorious because there are some good Bannurmaths. My age and physical ailments prevent me from attending the send-off function. But I wish with all my heart a fine span of peaceful but useful life ahead for this excellent judge".
