Can somebody explain when to use could have and could have been and under what circumstances? Please explain with an example.
Is it something to do with the active (could have) and the passive voice (could have been)?
I think, if I have understood correctly, that this rule also applies to (would have/ would have been) and (should have / should have been).

We can use 'could have' to talk about something somebody was capable of doing in PAST but didn't do. (Possible in Past)
We can use 'could have been' to talk about possible present situations that have not happened. (Possible in Present)
