NY S01789

Defines "strategic lawsuit against public participation" (SLAPP) as a legal claim arising from constitutional free speech on public concerns that lacks substantial basis in fact and/or law

Establishes "substantial basis" as a heightened pleading standard requiring demonstration of probability of prevailing, greater than plausibility or reasonableness

Allows prevailing defendants in SLAPP actions to recover costs and attorney's fees through motion or civil procedure rule adjudication, or demonstration the action lacked substantial basis in fact and law

Permits additional compensatory damages only if the action was commenced with intent to harass, intimidate, punish or maliciously inhibit free speech or petition rights

Requires any action under this section be filed no later than one year from the date the underlying SLAPP is finally determined in the defendant's favor
