There is no requirement to provide a prayer space so she wont lose on that. She may lose if she hasnt followed procedures in terms of banning prayer.
Despite what the media is claiming, the school is not being challenged for the lack of a prayer space. The issue of faith room was suggested by the pupils concerned after the school objected to praying during Ramadan.
The school is being challenged for banning praying in the pupil's own time (ie during lunch break). As I'm sure posters know, Islam requires prays five times a day, one of those times being just after lunch/early afternoon.
Apparently a teacher told two pupils to stop (before the ban), but they ignored the teacher. This was seen as disrespectful and the pupils were punished (as per the school rules). The pupils told their parents, who sought an interview with Birbalsingh. Apparently, this was ignored and it all blew up from there.
The governors confirmed that the ban on praying was to be permanent. Allegedly, they were given false information, including the nature of "tawba", which is asking Allah for repentance for not praying. They also did not consult or take witness statements from anybody else except Birbalsingh.
The judge will have all the details, including more than has been reported in the media and will, I'm sure, want to check the truth and timeline of what happened.
