A submission to this effect was made before Justice S Nagamuthu, when a batch of petitions by candidates whose names figured in the first provisional list of selected but deleted in an amended list published by the TNPSC later, came up for hearing.
In February 2013, the TNPSC conducted the written tests for nearly 340 engineers' posts in various departments. On October 4, 2013 the commission published a list of shortlisted candidates for certificate verification.
Assailing the action of the TNPSC as arbitrary and illegal, many candidates filed petitions challenging the amended list.
TNPSC admitted to a goof up on its part as two versions of keys of the question papers got interchanged.

"Since the error was deducted, an expert committee was constituted, and based on its opinion re-evaluation was undertaken by entering the correct key answers into the computer," it said.
The commission assured the court that the mistake had been rectified and the faulty list withdrawn, and added that no deserving candidate suffered because of the mix up.
He, however, said the TNPSC was not "absolutely blameless", noting that the commission should have owned up the error and should have made it public in the official website stating the reasons for revaluation.
"But, unfortunately the TNPSC had failed...Had this information been made public, I am sure many petitioners would not have rushed to this court with these writ petitions."
He then dismissed all the petitions, saying they warranted no intervention from the court.
