the committee against torture (cat) is a body of human rights experts that monitors implementation of the united nations convention against torture by state parties. the committee is one of eight un-linked human rights treaty bodies. all state parties are obliged under the convention to submit regular reports to the cat on how rights are being implemented. upon ratifying the convention, states must submit a report within one year, after which they are obliged to report every four years. the committee examines each report and addresses its concerns and recommendations to the state party in the form of "concluding observations." under certain circumstances, the cat may consider complaints or communications from individuals claiming that their rights under the convention have been violated.
