Justice D Krishnakumar sent assistant professor Nirmala Devi, who was in judicial remand, to a three-day CB-CID custody from June 27 for the purpose of taking her to Chennai and conducting the test.
The CB-CID, probing the sensational case, had moved the court, submitting that Nirmala Devi's voice samples were required to be taken to verify the voice in the audio clip, purportedly containing her conversation with the students.
It had said the testing facilities were not available in Madurai and wanted the court's permission to take her to Chennai.
The assistant professor was working with the Devanga Arts College in Aruppukottai, affiliated to the Madurai Kamaraj University (MKU). She was suspended after the scandal came to light.
