It indicted three former Maharashtra ministers and a minister in the Democratic Front government for their involvement in various cases of `corrupt practices and maladministration'.
The report also held social activist Anna Hazare, on whose complaints against the four the commission was set up in 2003, guilty on the same counts.
The report, however, exonerated state Tribal Development minister Vijaykumar Gavit. Chief Minister Vilasrao Deshmukh, who tabled the report in the lower House said a task force was being set up
The Sawant commission had submitted its report to the government on February 23.
