The right to a fair trial is a cornerstone of democratic societies. How a person is treated, when accused of a crime, provides a concrete demonstration of how far a State respects human rights. Detention is ‘arbitrary’, where there are often grave violations of the right to a fair trial. Detention and imprisonment, which may be lawful under national standards, are considered ‘unlawful’ under international standards. A fair trial is indispensable for the protection of other rights, such as the right to freedom from torture, the right to life, and the right to freedom of expression. This right should never be compromised. However, throughout the country, people are being detained and imprisoned without a fair trial. In these circumstances, many face torture and other forms of ill-treatment. The continued detention of Dr. Binayak Sen, Vice-President of India’s leading human rights organization, the People’s Union for Civil Liberties (PUCL), should trigger a debate, not only in Chhattisgarh, but also around the country, about whether and to what extent the right to a fair trial may be compromised in the name of security.
