Nations that have joined the treaty must submit regular reports to the Committee telling the legislative [l"ega"l], judicial ["court-based"], policy and other measures they have taken to give effect to the Convention. The first report is due within a year of the Convention being used in a country; afterwards, reports are due every two years or whenever the Committee requests. The Committee carefully reads each report and discusses its concerns and recommendations to the nation in the form of "concluding observations."
