The Health Services Union's national secretary Kathy Jackson -- last week the star witness in the prosecution of former MP Craig Thomson -- is currently embroiled in her own litigation with the union of which she remains notional head.

Crikey suggested on Tuesday that Jackson faced civil proceedings resulting from her time as head of the scandal-plagued union. Chris Brown, the HSU's acting national secretary, confirmed today that the union has two civil actions currently underway against Jackson, one in NSW and one in Victoria.
