Emphasising on the need for authenticity in the collection of statistics, President Pranab Mukherjee said that good data was important as its analysis plays a key role in shaping national policies.

“The efficacy of our policies, especially in the social sector, hinges on the quality of data collected by different government agencies. Good policies call for good data standards,” he said.

“Great emphasis must, therefore, be laid on the authenticity of the information gathered so as to form the basis of policy intervention,” Mukherjee told the 48th Convocation of the Indian Statistical Institute (ISI) here.

The President said that the Collection of Statistics Act, 2008, seeks to facilitate the collection of data on several socio-economic and other parameters.

It is the collective responsibility of the citizens and the seekers of information under this Act to ensure that correct and adequate statistics are furnished, he said.

The President advised exercise of due caution in analysing large data and drawing inferences.

“Capturing unstructured data and converting them into a structured format are technically challenging problems. They have to pursued in an enlightened manner.

“Drawing inferences call for adequate scrutiny of the theory requiring combined knowledge of the statistician and the subject expert,” he said.

“Enhanced capability of analysing large data had a positive act in our ability to formulate effective public policies as well improving transparency to ensure last mile connectivity,” he said.

Mukherjee said that improved ability to analyse data had led to an improvement in weather forecasting systems.

He said data mining and statistical techniques had been used to initiate counter terrorism programmes.

The Supreme Court said Friday that someone whose name does not figure either in an FIR or a chargesheet but whose role in an alleged crime surfaces during the course of a trial would be subjected to the said trial.

A constitution bench of Chief Justice P Sathasivam, Justice BS Chauhan, Justice Ranjana Prakash Desai, Justice Ranjan Gogoi and Justice SA Bobde said that the evidence against such an accused would be sufficient when evidence was being recorded and not at the stage of cross-examination of witnesses.

The court observation came while addressing five questions referred to it by a three- judge bench Dec 8, 2011, on the stage at which Section 319 of the Code of Criminal Procedure (CrPC) would come into play to try a person whose role in a crime surfaces during the course of a trial and at what stage would the evidence be read against such an accused.

Section 319 of the CrPC spells out the proviso for the joint trial of a person, who though not been named as an accused, appears, during the course of investigation or trial, to have committed a crime.

“Where, in the course of any inquiry into, or trial of, an offence, it appears from the evidence that any person not being the accused has committed any offence for which such person could be tried together with the accused, the court may proceed against such person for the offence which he appears to have committed,” Section 319 (1) says.

The five questions addressed the constitution bench were:

* At what stage can the power under Section 319 can be exercised?

* Does the word “evidence” used in Section 319 (1) only mean evidence tested by cross-examination or can the court exercise this power even on the basis of the statement made in the examination-in-chief of the witness concerned?

* Has the word “evidence” in Section 319 (1) been used in a comprehensive sense and does it include the evidence collected during the investigation or is it limited to the evidence recorded during the trial?

* What is the nature of satisfaction required to invoke the power under Section 319 to arraign an accused? Can this power be exercised only if the court is satisfied that the accused summoned will, in all likelihood, be convicted?

* Does the power under Section 319 extend to persons not named in the FIR or named in the FIR but not charged or who have been discharged?

Delhi Chief Minister Arvind Kejriwal on Friday again rejected the security cover that was offered to him by the Uttar Pradesh police, an Aam Aadmi Party (AAP) member said.

“He (Kejriwal) has refused to take any kind of security. His stand is clear,” an AAP member said.

According to Ghaziabad Senior Superintendent of Police Dharmendra Singh, the UP police had Thursday formally offered security cover to Kejriwal.

“On Thursday, we had offered security cover to the chief minister by sending him a formal letter. But we are still waiting for his final decision,” Singh said.

Singh added that two Gypsys, along with 28 police personnel, were to be deployed for his personal security.

On Wednesday, a few members of the Hindu Raksha Dal attacked the Aam Aadmi Party (AAP) office at Kaushambi which is located not far from Kejriwal’s residence.

As Devyani Khobragade heads back to India, her domestic worker Sangeeta Richard Friday broke her silence and claimed that she suffered while working for the Indian diplomat and asked other domestic workers not to let anyone “exploit” them.

In her first public statement, Sangeeta said she had decided to come to the US hoping to work for a few years to support her family and had planned to later return to India.

“I never thought that things would get so bad here, that I would work so much that I did not have time to sleep or eat or have time to myself,” she said in a statement released by the anti-trafficking group Safe Horizon, which is representing her in the case against Khobragade.

She said she had tried to return to India because of the treatment meted out to her while she was working for Khobragade.

“Because of this treatment, I requested that I return to India but that request was denied.”

“I would like to tell other domestic workers who are suffering as I did – you have rights and do not let anyone exploit you,” Sangeeta said.

Safe Horizon welcomed the indictment, saying it “demonstrates the seriousness with which the US government treats labor exploitation.”

“I hope that this case sends a clear message to diplomats and consular officials that the US will not tolerate the exploitation of workers and marks the beginning of an increase in prosecution of these cases,” said Avaloy Lanning, senior director of the organisation’s anti-trafficking programme.
