I believe the answer is:

lie up

I'm a little stuck... Click here to teach me more about this clue!

'enter' is the definition.
Both the definition and answer are verbs in their base form.
Maybe they are linked in a way I don't understand?

'dock and perjure oneself on trial' is the wordplay.
I cannot quite understand how this works, but
'perjure' could be 'lie' (I've seen this before) and 'lie' is found within the answer.
The remaining letters 'up' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

'the' acts as a link.

Can you help me to learn more?

(Other definitions for lie up that I've seen before include "Stay in bed" , "out of commission" , "(Of ship) go into dock" , "Berth" .)

I've seen this clue in The Independent.
