A crowd of angry NYC parents filled City Hall Park on Monday to protest the continued mask mandate for students under five

About a dozen NYC parents plan to file a lawsuit in Manhattan Supreme Court Monday seeking to overturn the requirement

The mandate was among the only Big Apple coronavirus restrictions not lifted last week, when Mayor Eric Adams said students over five could ditch masking

The parents plan to argue in court that the city must pass a law justifying the need to continue the mandate for children under five

A Change.org petition demanding an end to the rule has garnered 4,516 signatures as of Monday morning

The WHO says that children under five 'should not wear masks for a long duration or without supervision'
