Reserving orders on Thursday on a batch of petitions challenging a Tamil Nadu government order abolishing the Common Entrance Test and improvement test from the current academic year, the Madras High Court said it may strike down the part of the order pertaining to the CET.

"We can strike down the first part of the notification (pertaining to abolishing the CET) and allow the second part (doing away with improvement test) from next year," a division bench comprising Chief Justice Markandey Katju and Justice F M Ibrahim Kallifulla, said.

The judges said the orders will be pronounced very soon.

Over 200 students, who had appeared for the CET earlier this year for admissions to professional colleges in the state, had challenged the June 9 notification doing away with the two tests.

Turning down a suggestion from the state government that a 'scaling down' system could be adopted, the chief justice pointed out that the judiciary cannot legislate.

"Let the appropriate authority introduce the scaling down system. It will be very improper for the judiciary to cross its limits," the judges said.

On another plea by senior Supreme Court lawyer P P Rao that a judical order will allow departure from a Medical Council of India regulation, the bench said they cannot just do as they pleased as a lot of problems will be caused if they exceeded their limit.
