UK Unionist leader Bob McCartney has said he will not be resigning if he wins more than one assembly seat.
Bob McCartney is standing himself in six constituencies
Mr McCartney said he would take the secretary of state to court if he tries to prevent him having more than one vote if he win two or more seats.
Mr McCartney, who is standing himself in six different constituencies, was launching his "anti-manifesto".
He said it would be "absurd" to outline priorities for government when he would not be part of any administration.
He also rejected DUP claims that he could be "helping" Sinn Fein become the largest party after the 7 March poll, by taking votes away from them.
"How can a party that is totally dedicated to preventing Martin (McGuinness), Gerry (Adams) and co. ever being in government be helping them, when a party such as the DUP which has reversed the policies of a lifetime to welcome them is not helping them?" he said.
Mr McCartney also denounced the D'hondt system as an "affront" to democracy, described Sinn Fein as "not a fit partner for government" and blamed all four of the big parties for water charges and rates.
The UKUP is fielding a total of 13 candidates in the assembly election.
