Cite examiners because their work is relevant.
Cite examiners because you’ve used their results, conclusions or ideas in some way for your own research.
Don’t cite people if their work doesn’t connect. Don’t select examiners then look for ways to crowbar their research into yours. Don’t fall into the trap of thinking that you can only be examined by academics whose work is prominently in your bibliography.
There are more important reasons for considering academics as potential examiners than whether or not they feature in your bibliography.
There are better reasons for citing someone’s work than you’re thinking about them as a potential examiner.
