New York Gov. Andrew Cuomo has signed a bill that aims to deter rich and powerful litigants from bringing frivolous lawsuits meant to quell free speech.

Those cases are known as “strategic lawsuits against public participation,” or abbreviated as SLAPP. State Sen. Brad Hoylman, D-Manhattan, a sponsor of the legislation, says the measure gives New York one of the strongest laws in the United States against SLAPP litigation.
