J Jayalalithaa has been sentenced to four years in jail for corruption during her first term as Chief Minister of Tamil Nadu.
A court on Tuesday will hear her appeal against that verdict, which truncated her third term as Tamil Nadu's highest elected official.
The case was transferred from Tamil Nadu to Karnataka to ensure it would be free of the politics of her home state - ruled that Jayalalithaa, spent three crores on the wedding of her foster son in 1995.
The politician's lawyers had argued that the lavish wedding had been billed to the bride's family but the judge disagreed.
The full-fat expenditure on the wedding was presented by the prosecution as evidence that Jayalalithaa had illicitly acquired vast amounts of money while in office.
The judge said that the politician had collected assets worth 53 crores that could not be explained by her declared sources of income.
Along with Jayalalithaa, three of her aides were convicted, including Sasikala Natarajan.
