Ms. Nappinai’s expertise and proficiency in Criminal Litigation is reflected in her lasting reputation from her early days of practise at the Madras Bar and thereafter in succession at the Bombay Bar and now before the Supreme Court. She is Advisor – Maharashtra Cyber police for policies and investigations. Ms. Nappinai has lent her expertise in supporting the cause of enforcement in cybercrime cases since about 2003, with her continued training and capacity building initiatives for police and thereafter for judiciary.

She is reputed for her intense commitment to honesty and integrity in the handling of Criminal cases and advocacy and strategy skills in representing and handling several complex cases with especially those pertaining to white collar offences / corporate crime and fraud cases and cybercrime cases. She commenced with her internship under the tutelage of Shri. N. T. Vanamamalai, a renowned Senior Counsel at the Madras High Court and enrolled in 1991 and commenced practise with specialisation and focus on Criminal laws in 1991. Ms. Nappinai continued to lend her expertise in corporate criminal cases / cases of white collar offences during her brief stint with the law firm Amarchand Mangaldas Suresh A.

Ms. Nappinai continues to strongly propagate the strong principles imbibed from her seniors Shri. N. T. Vanamamalai and Shri. V. Gopinath, Senior Counsels, for practise of Criminal law with honesty and integrity and without shortcuts.

Whilst she has handled standard criminal cases including very intricate prosecutions in double murder trials, she carved a niche for her expertise in representing in cases pertaining to Corporate Criminal / White collar offences and Intellectual Property Rights enforcements and prosecutions. Her expertise in IPR cases led in fact to her interest and evolution as a pioneer in cyber laws since about 1995. Ms. Nappinai is now reputed for her handling of prosecutions and defence of cybercrime cases.

Ms. Nappinai propounds the cause for speedy and effective enforcement in Criminal matters. She believes that delays in concluding Criminal cases will negatively impact the very core of societal living and the need for laws and enforcement to be the bedrocks that guarantee individual safety and security. The very systemic failure in speedy and effective handling of Criminal prosecutions amount to a grave violation of Article 21 of India’s Constitution and breaches the fundamental guarantee of right to life and liberties.

Ms. Nappinai has drawn on these fundamental beliefs to support safe cities and online safety to ensure equal spaces and equality both in the physical and virtual worlds. Her writings point to the pitfalls and limitations in present systems and enforcement mechanisms, that fail to prevent or protect victims either in the physical or virtual worlds. Her work as Amicus Curiae before the Supreme Court and also in various Government Committees and her writings have carried forward the strong message for effective and pre-emptive protections for women and children particularly on digital domains, which lend themselves to much more abuse.

Ms. Nappinai lends her time and expertise in the field of Criminal laws honed from her internship period to her practise and specialisation since 1991 not only in fighting cases initiated by or against Corporates and business houses but also for social causes in protecting the rights of individuals in general and that of women and children, in particular.

Her recent initiative Cyber Saathi ( is meant to provide credible and reliable information on cyberlaws and to prevent commission of cybercrimes through awareness and to give initial guidance to victims and to lend courage and confidence in them through the assurance that they are not alone and that they do have and ought to seek remedies in law. Ms. Nappinai’s Cyber Saathi initiative is holistic and addresses preventive and protective measures; effective enforcement mechanism and also guides evolution of policies and legislations in the field of cyber laws and emerging technologies, through her research papers. Ms. Nappinai will continue to lend her expertise in Criminal laws and cyber laws including electronic evidence – appreciation, in training judges and police.
