from the star newspaper... his lawyer

"Lawyer Tan Sri Muhammad Shafee Abdullah, who is representing Najib, informed the court that he received news on Wednesday morning (Sept 11) from his client that he had been infected with conjunctivitis.
"I had a call this morning from my client (Najib) and his wife (Datin Seri Rosmah Mansor) that he has been infected with conjunctivitis," Shafee said, adding that it could have been due to the haze.

"He is now at home and will go to meet the specialist later today," he added."

From a professional point of view already can tell there is a problem with that claim. First, his lawyer is not a doctor so he can just simply make an assumption of patient sickness and believing what crap najis said. He should instead ask najis see a doctor and get a MC then tell the court
