The SNP is awaiting the outcome of a legal bid over its exclusion from Thursday's leaders' debate on BBC One.
An attempt by the Scottish National party to use the courts to ban the broadcast in Scotland of Thursday's BBC TV prime ministerial debate has failed.
Submissions have been made to a judge at the Court of Session in Edinburgh by the Scottish National Party and the BBC.
The party asked the Court of Session in Edinburgh to rule on whether the corporation had breached its rules on impartiality by excluding the SNP.
The SNP's QC said "there is no right to see an unfair debate" but the BBC insisted the demands were "impractical" and "ultimately pointless".
But this was dismissed by the judge, Lady Smith, after a two-day hearing.
The judge, Lady Smith, said she hoped to have a result by lunchtime.
If the SNP had succeeded the BBC warned the debate may not have been able to go ahead due to technical difficulties.
The SNP raised £50,000 to pay for the legal process.
The court papers state that the SNP is seeking an interim interdict against the BBC broadcasting the leaders' debate in Scotland if it does not feature the SNP.
It said it was not trying to stop the broadcast but the inclusion of an SNP politician was "a simple argument for fairness".

The BBC's lawyer Gerry Moynihan QC said it was "completely contrary" to the public interest.
He argued that the SNP had failed to take into account that, as well as being shown on BBC One, the debate will also be broadcast on the radio, the internet and Sky.
The QC told the court the Nationalists had a "considerable problem" in relation to the timing of the action, claiming they had "stood idly by" when the two earlier debates were held.
Earlier, SNP leader Alex Salmond said: "I think this has been one of the blackest periods in the BBC's history."
The SNP plan to distribute one million leaflets which display a BBC test card transmission saying: "Except for viewers in Scotland."
Labour said Mr Salmond was "more interested in trying to win newspaper headlines, because he knows he isn't winning the argument".
Conservative Scottish affairs spokesman David Mundell said Mr Salmond's attempts to be part of the UK leaders' debates was "nothing but posturing".
Liberal Democrat leader Nick Clegg branded the proposed legal action as a "measure of desperation".
In London, UKIP said it had written to the BBC Director General, Mark Thompson, giving him a deadline of noon to agree to include their leader Lord Pearson.
If the request is not met, the party said it would seek a judicial review of the decision by applying to the Administrative Court at 1400 BST.
