Securities market investigations can compel production of records, permit searches and seizures, and impose penalties for non compliance. Where the Board has reasonable grounds of detrimental transactions or contraventions it may appoint an Investigating Authority to require production of books, registers and records and to examine persons on oath; produced records may be retained for six months, certified copies provided, and the Investigating Authority may apply to the designated court for orders to enter, search and seize records where they may be destroyed or concealed, with seizure of listed public company records restricted unless insider trading or market manipulation is alleged.
