The Solomon Islands attorney general has advised the Electoral Commission, that former MP Jimmy Lusibaea is not eligible to contest the by-election for his constituency this year.
Lusibaea successfully contested the 2010 national elections only to lose his seat following an unlawful wounding conviction.
He was released by the Parole Board a year ago after serving only 41 days of a two year nine month prison sentence for shooting a hospitalised man in both knees and hitting a police officer over the head in 2000.
At the time, Lusibaea was a militia leader.
The attorney general, Billy Titiulu, says Lusibaea has been ruled out from recontesting his North Malaitan Constituency seat in the 1st of August by-elections.
He also adds he will not be able to contest any election until his sentence ends in December.
Lusibaea was one of two potential by-election candidates whose eligibility was shrouded in doubt, the other MP is Andrew Hanaria from the East Are Are constituency.
He was removed following a successful election petition taken up against his improper campaigning methods in 2010.
Hanaria's status for the August 1 election remains uncertain.
Nominations for candidates close on the 4th of July.
