In legal parlance, conspiracy as an offence is the agreement by two or more persons to do or cause to be done an illegal act or legal act by illegal means. The actual agreement alone constitutes the offence and it is not necessary to prove that the act has in fact been committed. See OBIAKOR V. THE STATE (2002) 100 LRCN 1716 @ 1719. Where persons are charged with conspiracy and with offence committed in pursuance of it as in the instant case, conviction for conspiracy is usually predicated on circumstantial evidence which must be of such a quality that irresistibly compels the Court to infer the guilt of the accused person. See POSU and ANOR. V. THE STATE (2011) 193 LRCN 52 @ 69. Conspiracy as rightly held by the lower Court is seldom proved by direct evidence but by circumstantial evidence and inference from certain proven acts. See ODUNEYE V. THE STATE (2001) 83 LRCN 1 @ 16.
