Jaitley called for the explanation from Defence Secretary R K Mathur and Ministry officials may also meet the Minister to give their side of the story, official sources said here.
The Defence ministry has told the Supreme Court in a recent affidavit in a promotion case related to Lt Gen Ravi Dastane that the alleged lapses which were made as grounds to impose disciplinary ban on Suhag were "premeditated", "vague" and "illegal".
Soon after the matter came to light, Gen V K Singh alleged that the "Defence Ministry affidavit is same as it gave to Armed Forces Tribunal under protective and conniving UPA".

He also justified his decision to impose a Discipline and Vigilance (DV) ban on Lt Gen Suhag saying that "If unit kills innocents, does dacoity and then head of organization tries to protect them, should he not be blamed? Criminals should go free!!."
The former Army Chief's comments came against the backdrop of reports that a unit under Lt Gen Suhag had allegedly carried out killings and daocities in the North East region. The Ministry, meanwhile, said it has adhered to its stand taken earlier on the issue related to imposition of DV ban on Lt.Gen Suhag by Gen V K Singh.
The sources said Government's stand in legal proceedings were based on considered facts and decisions and cannot be changed in different courts. The ban was imposed on Lt Gen Suhag for alleged "failure of command and control" in an operation carried out by an intelligence unit working directly under him when he was working as the then Dimapur-based 3 Corps commander.
In its last days in office, the UPA-II government had named Lt Gen Suhag as the Army Chief to succeed incumbent Gen Bikram Singh when he retires on July 31.
