Education Secretary Michael Gove has refused to intervene in the row of GCSE English grades, despite admitting pupils have been treated unfairly.
He told MPs it was up to England's exams regulator Ofqual to uphold standards and oversee marking and grades.
Schools have threatened legal action after grade boundaries were moved dramatically part way through the year.
Labour's Stephen Twigg said it was "rough justice".
