No, says the Court of Appeal in Singh v Morlands Primary School.
Whilst still employed, the Ms Singh brought a discrimination claim against her employer. Upon exchange of witness statements, she resigned claiming that the School had forced a particular witness to provide a statement of 'untruths', which she said amounted to a breach of trust and confidence.
In finding that Ms Singh could rely on such conduct in bringing her constructive dismissal claim, the Court of Appeal distinguished false evidence given in a witness statement, which is the subject of judicial proceedings immunity, from placing undue pressure on a witness to produce the witness statement, which is not. The latter conduct could give rise to a breach of trust and confidence, although the former could not.
