Andy Murray accused the International Tennis Federation (ITF) of being disrespectful after its decision to delay a decision on Aljaz Bedene's Davis Cup eligibility.
Bedene is set to miss Great Britain's Davis Cup final meeting against Belgium due to the ITF adjournment.
The 26-year-old was born in Slovenia and represented the country until earlier this year, when he was granted UK citizenship to compete for GB.
Having already played for the country of his birth, the ITF had ruled Bedene was unable to represent GB - leading to his case.
Murray, who will lead GB into the decider, criticised the ITF's approach.
"The fact that he had to go all the way over to Prague just to be told that they hadn't made a decision is a bit disrespectful towards him," Murray told the BBC.
"If they hadn't made a decision, they could have just said, 'We haven't made a decision yet - we're going to decide in March' and he could have stayed at home."
GB face Belgium in Ghent starting November 27, bidding for a first Davis Cup title since 1936.
