ICJ order comes as great relief to Kulbhushan's family, people of India: Sushma Swaraj

"I assure the nation that under the leadership of Prime Minister Modi we will leave no stone unturned to save #KulbhushanJadhav" Swaraj said in a follow up tweet.

Handing out India a big diplomatic victory, International Court of Justice (ICJ) on Thursday stayed the execution of former Indian Navy officer Kulbhushan Jadhav, ordering Pakistan not to hang him pending a final decision.

"Pakistan should not execute Jadhav pending final proceedings. The decision to stay Kulbhushan Jadhav's execution pending ICJ hearing is unanimous," Judge Ronny Abraham, President of the Court, said.

The court asked Pakistan to take "all measures at its disposal" to ensure that Jadhav is not executed till a final decision is taken.

The order comes ten days after India approached the UN's top court for "provisional measure" of protection -- an interim relief -- in the Jadhav case.

A Pakistani court had earlier sentenced him to death after being convicted of espionage.

Swaraj even lauded the officers of her ministry and said: "I compliment  my team of officers in the MEA for their tireless efforts and hardwork."

She even thanked Harish Salve for presenting the case of Jadav before ICJ.

Overruling Pakistan's contention that  ICJ  has no jurisdiction over the matter, an eleven-member bench said that it has prima facie jurisdiction in the case after Pakistan's failure to give consular access to India.

Hailing the ICJ order,  Indian Attorney General Mukul Rohatgi said: "Indian stand is victorious, congratulate all concerned persons, especially the External Affairs Ministry."

Fighting to save Jadhav, India on Monday told the International Court of Justice that there is an "immediate threat" that he may be executed any time that calls for urgent suspension of the sentence, media reports said.

"The situation is grave, it is urgent, and hence we approached this court at such short notice," senior lawyer Harish Salve, representing India, told the UN court as an an open hearing of the case was underway at the Great Hall of Justice at the Hague in Netherlands following India's challenge to Jhadhav's death penalty.

Jadhav, a former navy officer, was sentenced to death by a Pakistani military court last month after being convicted of spying.

Describing it as "farcical," India said Pakistan must ensure he is not executed until a court decision.

Salve said Pakistan had repeatedly denied consular access to India, which violates  the provisions of Vienna Congress and no document of Jadhav's trial process was given by Islamabad.

"The basic rights of Jadhav were thrown to the winds," he said.

Last week, after India challenged the death sentence, Pakistan was asked by the International Court to put it on hold.
