Lawyers representing the Khartoum Bahri Evangelical Church in North Khartoum are understood to have launched an appeal against a court decision to close it and confiscate remaining property.
On 18 February, police arrived at the church with an order from the Khartoum Civil Court to lock and seize the outer gates of the property.
Lawyers representing the church have issued a technical challenge on the wording of the order, with claims it does not identify the specific area of the church's property affected by the order.
The Bahri Evangelical Church is part of the Sudan Evangelical Presbyterian Church (SEPC) denomination and has been in an ongoing legal battle with the Sudanese authorities, who have attempted to sell church land to a Muslim businessman.
In December the church was partially destroyed and 37 congregants arrested. A day later Revd Yat Michael, a South Sudanese pastor from the South Sudan Evangelical Presbyterian Church (SSEPC) who preached at the Khartoum Bahri Evangelical Church, was also arrested by NISS agents.
Mervyn Thomas, Chief Executive of Christian Solidarity Worldwide (CSW), said: "We call upon the international community, and in particular the African Union, to hold Sudan to its obligations to protect the right to freedom of religion or belief and to guarantee the profession and free practice of religion as outlined in international statutes to which the nation is party."
