Additional Solicitor General (ASG) Sanjay Jain told a bench of justices Badar Durrez Ahmed and Sanjeev Sachdeva that these posts would be operationalised in two phases, half in 2016-17 and rest in 2017-18 after a review of the scheme.
The bench, while taking on record the ASG's statement, made it clear that these additional personnel, once recruited, would be used for crime investigation only.
It did not agree with the contention of senior advocate Chetan Sharma and advocate Shailendra Babbar, who appeared for Delhi Police, that the personnel would be needed when there would be a law and order situation.
"A person who is an investigator will only investigate and will not be used for law and order and will not be standing on roadside during VIP movement. The investigating staff or group should not be part of law and order duty," it said.
The court, meanwhile, expressed displeasure over the Centre "footballing" with the issue of sanctioning remaining 11,000 (approximately) posts as the Finance Ministry had sent the proposal back to the Home Ministry for reviewing whether increase in manpower was necessary and would advancement in technology suffice.
"This we are not happy with. This is footballing. Not happy with this part," the bench said.
Delhi Police in its proposal sent to the government had sought creation of 15838 posts, of which around 4000 were to be used for crime investigation alone.
The government's decision came after the court had on December 2 and earlier also expressed annoyance at the Centre's delay in sanctioning additional police for the city.
It had asked the central government to file an affidavit on whether it has funds to create additional force and whether it intends to create the additional force.
