On Tuesday as Asian Voice went to press, on the second day of the hearing, the Supreme Court was told that Ministers do not have the power to trigger Brexit without consulting Parliament.
The lawyer acting against the government said the "political significance" of June's vote was "irrelevant" to the legal battle.
But the government said a Parliamentary vote is not necessary before invoking Article 50 of the Lisbon Treaty.
Although the result could complicate the government's triggering of the process for the UK leaving the EU it is not expected to stop Brexit happening.
Campaigners, led by Ms Gina Miller say triggering Article 50 requires Parliamentary approval, and won at the High Court last month.
The government has appealed to the Supreme Court, whose decision is expected in January.
