National security is different from other situations. If national security is involved, someone may be able to do something that would otherwise be unlawful discrimination. If this applies, you will not win a case for unlawful discrimination.
But the person who you believe has discriminated against you has to show that what they did was proportionate for national security in that particular situation. Every situation has to be looked at separately.
Special rules apply to cases (whichever court they are in) if the person you believe discriminated against you says that national security is involved. If this applies to your case for discrimination, someone will tell you this and the court will give you advice about what to do about it.
