New Delhi, July 15 -- The Supreme Court on Tuesday sought the Centre's response to the Central Board of Secondary Education's (CBSE) decision to introduce the three-language policy from Class 6 from this academic year, after parents challenged the move, citing a shortage of textbooks and teachers for several Indian languages. A bench headed by Chief Justice of India (CJI) Surya Kant issued notice on two fresh petitions filed by parents of Class 5 and 6 students from across the country. The petitioners argued that the policy is difficult to implement as schools lack the infrastructure and manpower required to teach many of the prescribed languages. Senior advocates Gopal Sankaranarayanan and Anand Grover, appearing for the parents, told the court: "The CBSE has written to all heads of schools to ensure the books for the 22 scheduled languages are purchased. Even today, books are available only for 3 out of the 22 languages. This creates the complete impossibility of manpower and infrastructure for all schools." The fresh pleas, filed through advocates Shradha Deshmukh and Rohit Kumar Singh, argued that the CBSE circulars are based on an erroneous classification of English as a "non-native" language. "The entire edifice of the circulars (under challenge) rests on the constitutionally untenable premise that English is a 'non-native' language," the pleas said. The bench said: "The only issue to be determined is whether English can be considered as an indigenous Indian language. At one point of time, Parsi was the official language of our courts." The latest petitions come after the court, on May 27, issued notice on another batch of pleas challenging CBSE's earlier decision to mandate the study of two Indian languages from Class 9. On Tuesday, the ministry of education, CBSE, and NCERT filed separate affidavits in the matter filed by the parents of Class 9 students. NCERT said textbooks for Hindi, Sanskrit, Marathi and Urdu have already been prepared, while material for the remaining scheduled languages will be available by the end of this month....
