Prohibition of fraudulent market practices updated to enhance investigative powers and service of summons procedures Amendments clarify statutory cross-references for defined terms, expand the prohibition to cover dissemination of false or misleading information through any media intended or likely to influence investors, and enhance investigatory powers to call for records, apply for seizure orders where documents may be tampered with, retain seized materials until investigation concludes, and conduct searches and seizures in accordance with the Code of Criminal Procedure. Procedural updates modernize service of summons and notices by permitting delivery via courier, fax, electronic mail or messaging with digital signature requirements, affixation with witness reports, and newspaper publication as a last resort.
