Staring at the microwave doesn't make it reheat last night's leftover curry any quicker.

In the same way, looking longingly at the High Court hoping it will resolve the Citizenship Seven debacle swiftly could be a lost cause.

Chief Justice Susan Kiefel was pretty blunt when pulling down the shutters on the spectacle that's dominated the High Court's attention for the past three days.

"It is hardly necessary to say that the court is aware of the need to give its answers to these references with or without reasons as soon as possible," she s aid.

In other words — 'we get this is serious, but don't rush us'.

Nationals senator Matt Canavan's barrister, David Bennett QC, had moments earlier audaciously reminded the court of "the importance of an urgent decision".

The Citizenship Seven cases are a little more complicated than just picking up on "the vibe", to borrow from that constitutional tome The Castle.

With Parliament returning for another sitting fortnight, the citizenship cloud will continue to linger over Capital Hill as the High Court deliberates, providing further fuel to the Opposition in their campaign to destabilise the Government.

And the seven justices of the High Court have plenty to ruminate over.

Is ignorance of family history a good enough defence to allegations a politician has breached the constitution's citizenship rules? Deputy Prime Minister Barnaby Joyce and deputy Nationals leader Fiona Nash are relying on that.

Are the vagaries and quirks of foreign citizenship law enough to force a sitting politician out of parliament? Senators Matt Canavan and Nick Xenophon will be hoping the answer is "no".

Should they vindicate the choice of the former Greens senators Scott Ludlam and Larissa Waters to quit on the spot, after they discovered their dual allegiances?

Then, where do the wisest legal minds in the land even begin with the arguments put forward by lawyers for Malcolm Roberts — claims that entertained the public gallery and frustrated the High Court bench in equal measure.

Senator Roberts' case has prompted some accusations of hypocrisy.

A senator for a party that's campaigned on highlighting differences between people who are Australian-born and immigrants, chose to run the argument that he should not be treated any differently by the court just because he was born in India to a Welsh father.

While that's over-simplifying the Roberts case, it does give an insight into the constitutional complexity of the Citizenship Seven, and why it may be some time before their fate is known.

All the while, forces are being mobilised in north-east New South Wales just in case the Deputy Prime Minister is ushered out of the ministerial wing on orders of the High Court.

He's the odds-on favourite to retain his seat as the Member for New England if there's a by-election, but there's no doubt the campaign would get messy and become yet another distraction for a government often fighting for clear air.

In the meantime, imagine the theatre of a High Court decision against Mr Joyce in the middle of a parliamentary sitting week.

Imagine if it's during Question Time.

He's either on his feet, bellowing across the despatch box, or sitting behind Malcolm Turnbull on the frontbench.

Phones start vibrating. Pieces of paper are passed along the green leather seats. And the Opposition roars across the chamber.

"Stranger in the House!"
