Tennis Australia has filed an appeal against the International Tennis Federation's decision to approve Chennai as the venue for next month's India-Australia Asia/Oceania Group I Davis Cup tie.
The ITF will hear the appeal later this week and decide on Tennis Australia's request to shift the tie out of India on security grounds.
It had cleared Chennai as the host city despite the Australian federation's concerns about coming to India.
"The All India Tennis Association has been advised today by the ITF that Tennis Australia has officially appealed against the decision of the Davis Cup Committee to the ITF Board regarding confirmation of the Davis Cup venue as Chennai.
"ITF has confirmed that the appeal will be heard as soon as possible, definitely within this week," an All India Tennis Association said in a statement.
The AITA is confident that the tie will be held in Chennai from May 8 to 10 and is making arrangements for it.
