According to the New York Statewide Adoption Reform’s Unsealed Initiative, a pro adoption reform organization, “Once again Brooklyn Assembly member Helene Weinstein, Chair of Judiciary Committee, has stepped in to hold A909 from advancing to the assembly floor for a vote. She has stymied our legislation and continues to say the birth parents were promised confidentiality which we know is not the case.” A protest at her Brooklyn office has been scheduled for Sunday September 29th at 12:30 pm. Address: 3520 Nostrand Avenue (just south of Avenue V). 
Walter K. Olson, in his 2003 book The Rule of Lawyers: How the New Litigation Elite Threatens America's Rule, said “In New York, any proposed curbs on litigation must get past such committed opponents as Assembly Judiciary Committee chair Helene Weinstein, of counsel to her family’s personal-injury firm…” 
John Tierney, in an April 15, 2000 story in the New York Times had this to say about Weinstein's influence on public policy debates on tort reform, "It's rather like having a Microsoft lawyer in charge of the Congressional committee overseeing antitrust policy."
