As Jorus said, arresting him and moving him off your ship (then releasing him) is probably going to be your quickest solution. Otherwise you could move the ship to the ground and then submit a support ticket requesting that Cody be moved off your ship. Include the ship ID number and all the details if you go that route.
You will need to join the appropriate faction and satisfy the other criteria in order to arrest. The reason an admin can assist is because the kick passenger feature has been removed. You're best option is just to A/E.
Brazi is wrong that this is an IC problem that needs to be dealt with by IC means. Submitting a support ticket (using the Contact Support link at the bottom of the menu) is a valid method of resolving this situation.
That being said, using a faction to gain A/E privs and deal with it yourself might be an easier and more expedient course of action, as Elijah pointed out. But it is not a requirement.

Yes, there is a point, one I thought was at least as obvious as yours. Telling someone to ignore everything someone says followed by the same instructions that you told them to ignore is rather contradictory.
I realize that on the internet (and in swc in particular) there is a pressing need to be both vague and rude, but I think that it's important to be clear when you're answering someone's question, or correcting the answer to one, when in the question centre section.
