Yeh, former director-general of the bureau of investigation under Taiwan's "justice ministry," was accused of helping Chen allegedly cover up the latter's embezzlement of huge amounts of public money.
The ex-intelligence chief had disregarded his duties by providing Chen with classified information and documents on the latter's money laundering, the court said. Yeh's actions had seriously damaged the reputation of judicial departments, it said.
It further accused Yeh of lacking sincerity as he had changed his confessions several times, indicating that the former intelligence chief had never been regretful for his misconduct.
Yeh was chief of the bureau of investigation between August 2001 and July 2008. The bureau is mainly responsible for collecting information and detecting serious crimes such as embezzlement, drug and money laundering.
Meanwhile, prosecutors in Taiwan yesterday summoned a prominent businesswoman and her family as the corruption case against Chen Shui-bian continued.
The Special Investigation Unit under the island's prosecution authorities summoned Diana Chen, chairwoman of Taipei 101 Mall, to question her about alleged financial ties to Chen Shui-bian's family, according to media reports.
Six others, including Diana Chen's parents, were also asked to attend. SIU spokesman Chen Yun-nan described Chen and her parents as "witnesses" in the case.
