The Editors Guild of India has expressed concern over the “draconian provisions” of the Press and Registration of Periodicals (PRP) Bill, 2023, that can have an adverse impact on freedom of the press.
The Guild added: “Editors Guild of India would like the proposed bill to ensure that publishing of news in India remains free of encumbrances and intrusive checks on publishers by the Registrar, and that the primary emphasis of the Registrar and the PRP remains ‘registration’ and not ‘regulation’, as the latter has the potential of restricting freedom of the press.”
“In the definitions section, the term ‘specified authority’ gives power to government agencies beyond the Press Registrar, to conduct the functions of the Registrar, which could even include police and other law enforcement agencies. Given the intrusive, expansive, and vague nature of powers that the bill in any case allows to the Press Registrar, the power to further delegate this power to other government agencies including law enforcement agencies is deeply distressing,” the Guild said.
The statement says sections 4(1) and 11(4) allow the Registrar to deny the right to bring out a periodical and cancel the certificate of registration of a periodical to persons convicted of “terrorist act or unlawful activity” or “for having done anything against the security of the State”.
“Interestingly, the PRB Act, 1867, had no such provisions. Given the liberal and arbitrary use of UAPA (which is the basis for defining ‘terrorist act’ and ‘unlawful activity’), as well as other criminal laws, including sedition, against journalists and media organisations to suppress freedom of speech, the Guild is deeply concerned by the introduction of these new provisions, and the way they can be misused to deny the right to bring out news publications to persons who are critical of governments,” it said.
Among the other worrisome provisions listed by the Guild is Section 6(b), which gives power to the Press Registrar (as well as any other “specified authority”) to enter the premises of a periodical to “inspect or take copies of the relevant records or documents or ask any questions necessary for obtaining any information required to be furnished”

There are some advantages of the Digital Personal Data Protection Act (DPDPA), 2023. For instance, for the first time, personal data belonging to or identifying children will have to be classified separately, with such data carrying a greater degree of security and privacy. The law also seeks to reduce the rate and impact of data breaches targeting Indian businesses. The Digital Personal Data Protection law, however, goes a step beyond by imposing penalties for cases where data is breached as a result of a lack of implementation of adequate security controls. However, it could be said that the law isn’t balanced, because it provides wide exemptions to the processing of personal data to the government. For instance, data can be processed “in the interest of prevention, detection, investigation or prosecution of any offence … in India.” These kinds of exemptions are dangerous as they stand to legitimise widespread and unwarranted collection of data under the guise that such collection and processing may ultimately be useful for preventing or deterring a crime.
Security agencies will have significant authority to collect and retain any data whatsoever, as is typically the case with exemptions relating to the maintenance of sovereignty, integrity, security of the state, preservation of public order, prevention of offences, and incitement to commit offences. The law also exempts processing of personal data held outside of India. The government is also exempt from being required to delete any data that it possesses, regardless of the purpose it may have been collected for, on the request of an individual, or by way of a prescribed data retention period.
The government is not bound by purpose limitations, allowing data collected for one specified purpose be used for a new, incompatible purpose, which stands in contrast to the regulations imposed on businesses.
