A student petitioner, from Thakshila Vidyalaya Horana, complained to the Supreme Court that on July 8, 2009, she received a notification from the Educational authorities that the Z-score she received at the GCE Advanced Level, August 2008, was revised and reduced from 1.8874 to 1.8847.

In January 2009, she had been notified by the same Educational authorities that her Z-score was 1.8874, she had a legitimate expectation of being admitted to the Medical faculty. On July 8, 2009, she had received a back dated letter stating that her Z-score was revised and reduced to 1.8847. By the reduced Z-score, she is unable to enter the medical faculty.

The petition said that the reduction in the Z-score is arbitrary and without any reason or explanation.

The petition requested Court to direct the education authorities to admit the petitioner to the Medical Faculty, on the basis of the Z-score, she had received on the earlier occasion.

The petition was supported by Saliya Peiris. The petitioner is Maddhishi Kurukulasuriya of Panadura.

The Court said that it has to hear explanation from the Commissioner of Examinations, before granting leave to proceed with this petition. The Commissioner has to explain as to how the same candidate received two Z-scores. Senior State Counsel, Mahen Gopallawe was directed to ensure that the Commissioner of Examinations Anura Edirisinghe is personally present in Court on August 6, 2009.

The Bench comprised, Justice N. G. Amaratunga, Justice P. A. Ratnayake and Justice Chandra Ekanayake.
