The trial of Burmese opposition leader Aung San Suu Kyi resumed after a six-week adjournment.
Last week, UN Secretary General Ban Ki-moon visited Burma - officially known as Myanmar - but failed in an attempt to see Ms Suu Kyi.
The court at Insein prison in Yangon heard from legal expert Khin Moe Moe, a rare witness for the defence, after a ban on him appearing was overturned in early June.
The court initially banned three of four witnesses called to testify for the defence, later overturning the ban on Khin Moe Moe.
The prosecution has so far called 14 witnesses, fuelling opposition and international claims that the hearings are a show trial designed to keep Aung San Suu Kyi locked up ahead of elections scheduled for 2010.
Ms Suu Kyi faces up to five years in jail on charges of breaching the conditions of her house arrest after a incident in which US man John Yettaw swam to her lakeside home in May.
The Nobel peace laureate has spent 13 of the past 19 years in detention since she refused to recognise the NLD's landslide victory in the country's last democratic polls in 1990.
