Two Ballarat police officers accused of using excessive force against vulnerable women are taking the state's anti-corruption body to the High Court next month.

It will be the first time the core function of the Independent Broad-Base Anti-Corruption Commission will be tested at such a level since it was set up in 2012.

The two officers, a man and woman from the country Victorian station, were accused of excessive force against a number of women. The allegations include kicking and stomping on a mentally unwell woman in January last year as she lay handcuffed on the ground in the station, a previous court hearing was told.

The officers have been fighting for the case to be investigated in secret ever since IBAC announced in April it would hold public hearings to explore the allegations, as well as the proficiency of the force's internal reporting system and whether the police station has a cultural problem.
