The document is a letter from the Assistant Registrar of the Supreme Court of India to Om Prakash regarding a curative petition filed. The letter notes that the curative petition is defective for three reasons: it does not include the required certificate of a Senior Advocate, and is missing two additional paperbooks from related writ and review petitions. Om Prakash is requested to cure these defects within 28 days or the petition will be dealt with according to Supreme Court rules.
