There is a demand in Tamil Nadu to make Tamil the language of Madras High Court. According to the constitution of India English is the language of High Courts and Supreme Court. Making Tamil the language of Madras High Court requires constitutional amendment.
If UPA decides to go for constitutional amendment to make Tamil the language of Madras High Court other states will demand their languages be made languages of their High Courts. The amendment will have to apply all High Courts.
If the amendment is passed it will create the problem of translation of High Court judgments when people want to appeal to Supreme Court against High Court judgments. With English as the language of High Courts it takes several days to get a copy of the judgment. It will take more days to translate the judgment from state language to English. Computers can be used for translation but someone has to check it for accuracy. We have the example where computer translated “out of sight out of mind” as “invisible idiot”.
