Two Muslim schoolboys barred from classes because they would not shave off their beards have now been sent home from school.
Both 14-year-olds had been placed in "isolation" from the start of the new term at Mount Carmel RC High School in Accrington.
Talks were held with the families of the two boys to resolve the problem but neither side backed down and the school has now decided the pupils can only return to school when they are clean-shaven.
Headteacher Xavier Bowers has stressed that the matter is not one of religion but about dress code.
In a statement he said: “At Mount Carmel RC High School, we believe that it's important to be clear about what we expect from students in all aspects of school life, including appearance and uniform.
“When disputes arise we do our best to deal with them in a reasonable and understanding manner and to resolve them to everyone's satisfaction if at all possible.
“Pupils and parents are made aware of the rules on appearance and uniform before they start attending the school, know that they apply to everyone and are regularly reminded of this.”
