The accused were found guilty by a jury of offences related to the importation of approximately one kilogram of heroin from Thailand.
Prior to sentencing, one of the accused applied for an inquiry into a juror who had sent an email to Crown counsel after the verdict expressing admiration.
The court dismissed the application, finding no evidence of pre-verdict communication or reasonable apprehension of bias.
On sentencing, the court emphasized denunciation and deterrence for heroin importation.
Igbinoba, who acted as a sophisticated conduit, was sentenced to 11 years.
Godwin, who was the intended recipient and more senior participant, was sentenced to 12 years.
Both received credit for pre-sentence custody.
