The Supreme Court said Thursday it has postponed the sentencing hearing of former first lady Kim Keon Hee's corruption trial in order to refer the case to its full bench.

The hearing had been scheduled for 2 p.m. Friday following deliberations by Division 2 of the court. The new date was not immediately disclosed.

The trial centers on charges that Kim, the wife of former President Yoon Suk Yeol, was involved in a stock price manipulation scheme, accepted luxury gifts from the Unification Church and received free opinion poll results from a self-proclaimed power broker.

The full bench referral was likely caused by conflicting rulings from lower courts regarding the opinion polls, as Kim was acquitted while her husband was found partially guilty on the same charge.
