Ten Supreme Court lawyers today served a legal notice on the government to know what necessary steps have been taken to prevent eavesdropping and recording of private telephone conversations and to ensure right to privacy.

Advocate Mohammad Shishir Manir, head of Law Lab -- an organisation conducting research on law and constitution, sent the legal notice on behalf of the lawyers to the authorities concerned, requesting them to inform about the measures taken to this effect in seven working days.

If the respondents do not provide the information in seven days, the notice senders will have no other option but to take legal action against them for getting proper redress, without making any further reference, Shishir Manir said in the legal notice.

The lawyer, in the legal notice, said that in recent years, they have come across numerous incidents of eavesdropping and recording of private telephone conversations from various newspaper reports published in national dailies including The Daily Star.

The respondents who have been served the legal notice are secretaries to the ministry of posts, telecommunications and information technology, post and telecommunication division, information and communication technology division, and chairman of BTRC.

The 10 lawyers who served the legal notice are: Rezowana Ferdose, Uttam Kumar Banik, Shah Navila Kashphi, Farhad Ahmed Siddiky, Mohammad Noab Ali, Mohammed Ibrahim Khalil, Mustafizur Rahman GM Muzahidur Rahman, Imurl Kayes and Eakramul Kabir.
