Legal Advise needed, Comment..??

A ‘APP’ under Bihar judiciary has been arrested by vigilance taking some bribe. His point is that he was not receiving any particular salary by Bihar government. He was on temporary basis for 5 years and he was receiving only commissions on every cases which was under him by government.

His argument is that if he can prove that he’s not a government employee, he will not come under the vigilance department.

Is this possible or not, and give reasonable suggestions. Comment..!!
