Mr Sakwiba Sikota’s law firm, Central Chambers, and others had represented Dr Kaunda pro-bono in misprision of treason and citizenship and other cases in the late 1990s but later claimed US$1,200.
The claimed figure was later reduced to US$645 after an assessment.
The case was handled by five Supreme Court judges that included retired Deputy Chief Justice Marvin Mwanamwambwa and deputy Chief Justice Michael Musonda, Mumba Malila, Charles Kajimanga and Nigel Mutuna.
In its judgment, the Supreme Court set aside the High Court default judgment on grounds that the evidence indicated that Central Chambers, in 1998 undertook to represent Dr Kaunda on pro-bono basis.
The evidence was pursuant to the United National Independence Party’s Central Committee meeting minutes of February 28 and March 04, 1998.
The Supreme Court said the claim for Dr Kaunda to pay legal fees was tainted with irregularity.
