No provision of this Act shall be construed to require the assignment or transportation of students or teachers in order to overcome racial imbalance.

Notwithstanding any other law or provision of law, in the case of any order on the part of any United States district court which requires the transfer or transportation of any student or students from any school attendance area prescribed by competent State or local authority for the purposes of achieving a balance among students with respect to race, sex, religion, or socioeconomic status, the effectiveness of such order shall be postponed until all appeals in connection with such order have been exhausted or, in the event no appeals are taken, until the time for such appeals has expired. This section shall expire at midnight on June 30, 1978.

The rules of evidence required to prove that State or local authorities are practicing racial discrimination in assigning students to public schools shall be uniform throughout the United States.

The proviso of section 407(a) of the Civil Rights Act of 1964 [42 U.S.C. 2000c–6(a)] providing in substance that no court or official of the United States shall be empowered to issue any order seeking to achieve a racial balance in any school by requiring the transportation of pupils or students from one school to another or one school district to another in order to achieve such racial balance, or otherwise enlarge the existing power of the court to insure compliance with constitutional standards shall apply to all public school pupils and to every public school system, public school and public school board, as defined by title IV [42 U.S.C. 2000c

Notwithstanding any other provision of law, after June 30, 1974 no court of the United States shall order the implementation of any plan to remedy a finding of de jure segregation which involves the transportation of students, unless the court first finds that all alternative remedies are inadequate.

In the formulation of remedies under this chapter the lines drawn by a State subdividing its territory into separate school districts, shall not be ignored or altered except where it is established that the lines were drawn, or maintained or crossed for the purpose, and had the effect of segregating children among public schools on the basis of race, color, sex, or national origin, or where it is established that, as a result of discriminatory actions within the school districts, the lines have had the effect of segregating children among public schools on the basis of race, color, sex, or national origin.

Notwithstanding any other law or provision of law, no court or officer of the United States shall enter, as a remedy for a denial of equal educational opportunity or a denial of equal protection of the laws, any order for enforcement of a plan of desegregation or modification of a court-approved plan, until such time as the local educational agency to be affected by such order has been provided notice of the details of the violation and given a reasonable opportunity to develop a voluntary remedial plan. Such time shall permit the local educational agency sufficient opportunity for community participation in the development of a remedial plan.
