If you look at the logistics in heaving another language as official language than not only Marathi, Kannada and Malayalam should also be the official language of Goa too. The fun starts than, the establishments will have their food names in Konkani, Marathi. The law books will have to be re-written in all languages. The ministers and MLAs name plates will have to be in both languages. The road signs will look colorful, the bus, trains stations, bus stands will be with different languages. To add insult to injury you will have to use English because of tourists and Hindi because it is the national language. Goa will be colourful.
