Illegal aliens are “people” under the Constitution and are protected by that document.
Can the US military ask your citizenship? The Department of Motor Vehicles? The Social Security Administration?
FYI: In this particular case, the privacy of the students would be protected and no action would be taken against them. As a taxpayer, I would like to know what illegal aliens are costing. What are my rights?
The Supreme Courts decision in Plyler v. Doe, 457 U.S. 202 (1982), said only that children may not be denied education on the basis of their immigration status. Subsequently, a 1997 district court case (League of United Latin American Citizens v. Wilson, 997 F.Supp. 1244 (C.D. Cal. 1997)) declared unconstitutional a provision in Californias Proposition 187 that required schools to verify the status of schoolchildren because the Court found that the intent of the requirement was to deny the students access to a public education. Presumably, a state or local government could inquire about legal status for another, constitutional reason (such as to seek federal reimbursement).
