Federal judge today blocked the application of a law to Texason the basis of which all the school classes should be posted on 1 September.

Judge Fred Biri issued a preliminary mandate by banning the application of the law after the appeal filed by the families of students belonging to different religions. The law is unconstitutional, “in an unacceptable way, on theological issues and officially favors Christian doctrines, at the expense of other” religions, Biri said in his decision, an area of 55 pages.

The posting of the ten commandments in the classrooms may send “a message of exclusion” to children of other religions, giving them the impression that “they are strangers who do not belong to their school community,” he said.

Rabbi Mara Nathan, who had appealed against the law, welcomed the court ruling. “Children’s religious beliefs should be cultivated by their parents and religious communities and not by political persons or public schools,” he said in a statement.

Rachel Laser, the president of the “united Americans for the separation of Church and State” also welcomed the decision that “sends a strong message across the country that the government must respect every student’s religious freedom in public schools”.

Another federal judge had blocked a similar law in Louisiana in November, another conservative state of the Southern US. That law was considered to violate the first amendment of the Constitution prohibiting the establishment of an official religion.

Religious freedom and the separation of the Church from the state are fundamental principles in the US. In 1980, the Supreme Court had ruled an unconstitutional a law of Kentucky, which provided for the posting of the ten orders in the classrooms.
