The Supreme Court is expected to hear the injunction application filed by the National Democratic Congress (NDC) lawmakers against the e-levy, today Wednesday May 4.
The controversial levy started on Sunday May 1 amidst public outcry.
The NDC heavily opposed the introduction of the levy.
In their view, it is punitive and amounts to double taxation. The bill was passed by Parliament on Tuesday March 29 after the Minority staged a walkout.
They walked out after their leader Haruna Iddrisu said the NDC MPs remained united in opposing the policy.
On Tuesday April 19 they filed an application at the apex court to block the commencement of the e-levy deductions. But the the Ghana Revenue Authority (GRA) went ahead to start implementation of the Policy on Sunday May 1.
The NDC MPs, while filed the injunction application were Haruna Iddrisu, MP for Tamale South, Samuel Okudzeto Ablakwa, MP for North Tongu and Mahama Ayariga, MP for Bawku Central.
