While the NDA was in Opposition, Badal opposed FDI, and sided with political ally BJP.
Parkash Singh Badal along with his wife Surinder Kaur, son Sukhbir Singh and seven others were booked under various provisions of the Prevention of Corruption Act in 2003. After a seven year long case, all accused were acquitted by a local court in Mohali in 2010 due to the lack of incriminating evidence. In 2007, 11 key witnesses retracted their statements before the Special Court set up in Ropar district.
On December 11, 2011, Badal was bestowed upon the title of Panth Rattan Fakhr-e-Qaum(literally Jewel of the religion, pride of the community) by the Akal Takht. Prakash Singh Badal has always been praised for his simplicity.
