Common wealth games

Dear CCI collegues..

I have a doubt that : The umpires , judges , referees, all the other dignotories who took part in the Common wealth games which were held in Delhi, for conducting the games,....

Whether the remuneration which was paid to them is Taxable in India.....

If not How it is not and whether there are any reliefs to them....

Whether TDS has to be made to those people.....

Thanks in advance......
