With their retirement, the judges strength of the court will come down to 49 against the sanctioned 75.
Those who will retire on different dates during May are Justices S Nagamuthu, S Palanivelu, T Mathivanan and P Devadass.
They were given a farewell today as it is the last working day for the court which will remain closed for summer vacation from May 1 to May 31.
The collegium of the high court had earlier this year forwarded a list of 11 names for appointment as judges.
