Point of order? That could be unpolitic (9)

Ross

I believe the answer is:

punctilio

Here is my best explanation:

'point of order?' is the definition.
(a punctilio is a petty or minor point)

'could be unpolitic' is the wordplay.
'could be' indicates anagramming the letters.
'unpolitic' with letters rearranged gives 'PUNCTILIO'.

'that' acts as a link.
