Libya has named Sreenivasa Pammaraju Rao, an Indian judge, to sit on a tribunal that will look into last year's detention in Geneva of a son of Libyan leader, Moammar Gaddafi.
The Swiss foreign ministry said at the end of August that Elizabeth Wilmshurst, a British lawyer, would be Switzerland's arbitrator on the panel, which will be located in London.
Neither Rao, a 67-year-old expert on public prosecution who currently works in Qatar, nor Wilmshurst would comment on the appointment.
The tribunal is a condition of the Swiss-Libyan accord signed on August 20 by Swiss President Hans-Rudolf Merz, who has come under fire for apologising to the Libyan authorities for the "unjustified and unnecessary" measures by authorities in Geneva against Hannibal Gaddafi.
Gaddafi and his wife were detained by Geneva police after accusations they had mistreated two domestic staff. Charges were never brought against them.
