20 U.S.C. § 1717 — Reopening proceedings

A parent or guardian of a child, or parents or guardians of children in a similar situation, may seek to reopen or intervene in carrying out a current court order if the child is transported to a public school under that order. An educational agency^* may do the same if it is subject to a court order or to a desegregation^* plan under title VI of the Civil Rights Act of 1964 [42 U.S.C. 2000d et seq.] that was in effect on August 21, 1974, and was intended to end segregation^* of students based on race, color, or national origin. The request may be made only if the travel time or distance is so great that it risks the student's health or significantly interferes with the student's educational process. This section does not define "similarly situated," "educational agency," "court order," "desegregation plan," or "educational process."
