In November 2007, while Tsai was vice defense minister,
Aerospace Industrial Development Corporation won a bid to produce equipment for the
Republic of China Armed Forces. Kuomintang legislator
Tsai Chin-lung had reviewed military equipment, found the specifications to violate the contract terms, and ordered AIDC to suspend production. Michael Tsai and DPP lawmakers
Ho Min-hao and
Hsieh Ming-yuan along with AIDC chairman Lo Cheng-fang, accused Tsai Chin-lung of interference on behalf of
SYM, the company that had lost the contract. The Taipei District Court ruled in September 2011 that the claims against Tsai Chin-lung were unsubstantiated and ordered all four accusers to publish a public apology. In April 2009,
Next Magazine reported that Tsai was responsible for selling military ranks during his tenure as
Minister of National Defense. Tsai denied the allegations and sued the publishers for defamation. Tsai released his memoirs,
God Bless Taiwan in April 2011. Shortly before its official publication in 2013, Tsai was accused of leaking state secrets. In August 2014, Tsai and
Chiou I-jen were accused of violating the Classified National Security Information Protection Act. The
Supreme Court found both not guilty in November 2015. ==References==
