The Special Court formed to try former President Pervez Musharraf in his treason case adjourned its proceeding till Jan 6 after ex-military ruler did not appear before it and was rushed to hospital on Thursday (January 2) after suffering a heart problem on his way to court.

Musharraf, 70-year-old, had been summoned to the special tribunal in Islamabad after failing to show up for two previous session due to security threats against him.

On his way, Pervez Musharraf complained about chest pain, following which his convoy was immediately diverted to Armed Forces Institute of Cardiology for a medical checkup.

Earlier, the court had to take recess after Musharraf’s lawyers staged walkout citing threats to their lives.

Musharraf's team says the allegations, which relate to his imposition of emergency rule in November 2007, are politically motivated and his lawyers have challenged the authority of the three-judge tribunal.

Musharraf faces the death penalty over suspension of the Constitution and imposition of emergency rule by him in 2007.

Earlier on Thursday his lawyers walked out of court, complaining of being threatened and harassed.

He is the first former army chief to go on trial in Pakistan, setting up a potentially destabilizing clash between the government and the military.
