Aziz Dweik, speaker of the Palestinian Legislative Council, was arrested on June 16, last year as Israel staged a massive manhunt for three teenagers who were snatched from a road in the southern West Bank by Palestinian militants linked to Hamas.
During the search, which lasted until June 30 when their bodies were found, Israel arrested hundreds of Palestinians, most of them members of Hamas.
The crackdown - the biggest in a decade - triggered a surge of rocket fire from the Gaza Strip, the Islamist movement's stronghold, which ultimately led to a 50-day war in and around the coastal enclave, the third in six years.
The council has not met since 2007 following a major rift between the Fatah movement of Palestinian president Mahmud Abbas and its Hamas rival, which saw the Islamist movement forcibly expelling Fatah loyalists from Gaza.
