10.45AM: Justice Arifin reads Anwar’s defence questioning Saiful’s conduct of bringing the KY jelly and the Pusrawi doctor claiming that a plastic object had been inserted into his anus.

10.43AM: The judge is now focusing on the issue of Saiful’s credibility.

The only case that will be heard in Federal Court 1 is Anwar's appeal. The court is normally used when Chief Justice Arifin is presiding.
8AM: All eyes will be on the five-member Federal Court bench that will decide on whether Anwar Ibrahim's appeal against the conviction and sentence for sodomy will be upheld.
Led by Chief Justice Arifin Zakaria, the panel is expected to take an hour to deliver its verdict beginning at 9am.
It is unknown as to who among the five-member panel will write and read the judgment.
It also remains uncertain whether the decision will be unanimous or if there will be any dissenting judgment similar to the Federal Court decision in 2004 which acquitted Anwar.
Should the Federal Court maintain the conviction, then the panel will listen to submissions from Shafee Abdullah, the private lawyer who has been appointed by the government to lead the prosecution.
The submissions are necessary because the prosecution made a cross-appeal to increase the five-year jail sentence handed to Anwar, 67, by the Court of Appeal.
Anwar is staring at a maximum jail sentence of 20 years.
After Shafee's submission, Anwar's defence team, led by former Federal Court judge Gopal Sri Ram, will submit their replies. Shafee will then make one final replay.
The defence and prosecution team have already been asked to prepare written submissions, in case the conviction is upheld. Some observers believe this is a bad omen .
Should Anwar be found guilty, the apex court, after hearing the submissions, will decide on sentencing and bring an end to a case that has dragged on for seven years, involving 27 prosecution and eight defence witnesses.
