In In re King v. Board of Education of the City School District of the City of New York, (App. Div., June 24, 2021), a New York appellate court upheld randomized in-school Covid-19 screening tests for students in parochial and private schools. The court said in part:
We reject respondents' contention that section 912 must be construed as permitting only health screening tests which primarily benefit the child, so as to avoid running afoul of the Establishment Clause. Respondents do not explain how randomized in-school Covid-19 screening tests would have "a primary effect that advances religion," the touchstone of the Establishment Clause.
