Bengal Chief Minister Mamata Banerjee received her honourary Doctorate of Literature (D.Litt) degree from the Calcutta University today as a court heard a petition which challenged the decision and called the Chief Minister "ineligible" for the honour. A retired vice-chancellor of the North Bengal University had urged the court to put brakes on the Calcutta University's decision, saying it was "against public interest" -- a stand the state has vehemently opposed. The court heard the arguments yesterday for three hours and another hearing was slated for today.
