Manchester's Crown Square Crown Court has been forced to shut again after four people tested positive for coronavirus.
The Spinngingfields courthouse had to close last Thursday (August 6) after a member of staff contracted the virus.
Lawyers and members of the public were able to return at 2pm, after a deep clean of the building was carried out.
But on Monday morning, the court had to close again, after a further three people tested positive for Covid-19 over the weekend.
It is understood that all cases listed at the court today, have been adjourned and will be re-listed.
The Northern Circuit, who represent barristers in the north of England, said the courthouse would be undergoing a deep clean.
They said court staff were awaiting advice about the next steps that will need to be taken for the building to re-open.
On Twitter, they wrote: "Following three people having tested positive for Covid-19 at Crown Square, the court will be closed on Monday.
"Efforts are being made to re-list some cases at Minshull St if possible.
"Obviously, apart from deep cleaning, advice is being sought in relation to the steps that will be needed to address this incident.
"Staff will be present at the building to let anyone who arrives know of the situation.

"The Northern Circuit sends best wishes to those affected and wishes them a speedy recovery."
Five of the court's 15 rooms were due to be holding cases throughout the day, with a mix of trials and sentences scheduled.
In the past few weeks, barristers have been expected to attend court physically for cases, unless they have a good reason not to.
During the height of the lockdown, most cases were conducted using video conferencing.
Under new security measures in line with the pandemic, anyone entering the court via the public entrance is asked whether they had coronavirus symptoms before entering.
More recently, court users have been asked to wear masks on the concourses and in other public areas.
Barristers are allowed to remove their masks in court rooms to conduct their case.
A spokesman for Her Majesty's Courts and Tribunals Service said: “Manchester Crown Court is being deep cleaned today after three people working there tested positive for COVID-19 at the weekend.
“We are following public health guidelines to ensure the safety of all court users and the site is due to reopen tomorrow.”
