A report was submitted by prison authorities following directions earlier this month from HC, which is hearing a plea filed by Mukerjea seeking bail on medical grounds.
Mukerjea, who is lodged at the Byculla Womens' prison here since her arrest in August 2015, had approached the high court seeking bail on medical grounds and on the basis of merit.
Special CBI Judge JC Jagdale directed the prosecution to take note of Rai's application and submit its reply by January 19.
In her application, Mukerjea said that jail authorities were asking her to wear the convict's uniform even though she is an under-trial accused. The next date of hearing on her application is January
The prison authorities were asking her to wear the convict's uniform of green sari even though she was only an under-trial accused, she said in her petition.
The 65-year-old, who is in jail since his arrest by the CBI in 2015, was Sunday admitted to the state-run J J Hospital after he complained of chest pain.
Mukerjea had demanded access to the personal diary maintained by sub-inspector Ganesh Dalvi, a prosecution witness who was part of the team that arrested prime accused Indrani Mukerjea's driver.
