COLUMBIA, S.C. - South Carolina has refused to rehear a Republican activist’s arguments accusing Gov. Nikki Haley of breaking ethics laws.

The state Supreme Court on Friday turned down the request from John Rainey.

Rainey sued Haley in 2011, accusing the GOP governor of improper lobbying while working as a hospital fundraiser and for a highway engineering firm while representing Lexington in the state House.

A judge threw out Rainey’s case, which he appealed. Rainey also lodged a parallel complaint with a House ethics panel, which ultimately cleared Haley of all allegations last summer.

Last month, the high court ruled that legislators, not the legal system, should handle citizen complaints against their elected representatives.

Haley’s office has called the suit a political vendetta and a waste of taxpayer money.
