Schoolgirl Error
Unfortunately this lady appears to have made several schoolgirl errors in bringing her case which Im guessing will make it doomed to failure, albeit its not clear what elements of her case remain from quick skim of the judgement.
It looks like the initial judgement for "interim relief" was for a stay execution.
2 obvious errors :
1. She is confusing or attempting to conflate "worked for" with "employed by"
2. You never ever send 116 "stream of consciousness" emails to a tribunal, you make limited and deliberate updates of material evidence.
3. Those 116 mails suggest she is taking it personally. No matter how personal it is losing your objectivity is a recipe for disaster. By all means be angry - but dont let that stop you acting with a clear head with the tribunal.
I dont hold out much hope for her no matter how justified or not her case might be.
She might be better off researching her agency employer who is using the mini-umbrella's and dobbing them into HMRC. She may not get much satisfaction from that route either but it would have been worth a punt at less cost and effort to her.
