"Faith" schools are popular because they can use their control over admissions to preferentially admit the easy-to-teach kids from supportive middle-class backgrounds, while tending not to admit kids who are less easy to teach. Thus, "faith" schools tend to have, for example, significantly lower rates of pupils eligible for free school meals than their surrounding areas.
Doing this is actually against the school's admissions code and is against the law. But, "faith" schools nearly all do it because that's what makes them academically successful and popular with parents (and thus with politicians).
The British Humanist Association, who are of course opposed to "faith" schools on principle, have launched a series of appeals to the courts to overturn unfair admissions practices by such schools.
So far they have pursued 42 such cases in the courts and won all 42 of them!
The government really don't like that. So Education Secretary Nicky Morgan has just announced plans:
"stopping vexatious complaints against faith schools from secularist campaign groups".
Interesting word that, "vexatious". In a legal context "vexatious" means (Oxford English Dictionary):
"Denoting an action or the bringer of an action that is brought WITHOUT SUFFICIENT GROUNDS FOR WINNING, purely to cause annoyance to the defendant" (added emphasis).
Now, bearing that emphasized phrase in mind, does 42 victories out of 42 suggest a "vexatious" litigant? Methinks it doesn't.
Methinks the government and the faith schools are "caused annoyance" because they don't want to have to obey the law, but want to continue their nefarious practices.
