ALBANY – Long Island teachers upset over the slow pace of contract talks had a free-speech right to legally park in front of the school as a public protest, but lost their First Amendment privileges by disrupting traffic and potentially endangering children and educators, a divided Court of Appeals held on Tuesday.

In Matter of Santer v. Board of Education, 51, and Matter of Lucia v. Board of Education, 52, the state’s highest court reversed a mid-level appellate panel and reinstated fines that an arbitrator had imposed on two teachers.
