Mr Johnson's government prorogued parliament earlier this month until mid-October.
It means MPs are not sitting for more than a month in the lead-up to the current Brexit deadline of October 31st.
Boris Johnson has insisted the five-week break is a routine move to allow for a Queen's Speech to set out his new government's agenda.
However, opponents of the move have claimed the move is aimed at silencing the parliamentary debate on Brexit.
The case was taken to the Supreme Court after two conflicting rulings in lower courts.
Judges in Scotland said the suspension was unlawful, following a case led by SNP MP Joanna Cherry.
However, judges at the High Court in England had earlier found Mr Johnson's decision was a 'purely political' one and dismissed the case.
The English case was launched by anti-Brexit campaigner Gina Miller, who was later joined by the likes of the former British prime minister John Major.
Opening the hearing last week, President of the Supreme Court Brenda Hale said: "That this is a serious and difficult question of law is amply demonstrated by the fact that three senior judges in Scotland have reached a different conclusion from three senior judges in England & Wales.
"The Supreme Court exists to decide such difficult questions of law."
She stressed that the court is not concerned "with the wider political issues which form the context for this legal issue" - noting it will not determine when and how the UK leaves the EU.
