No, she is not obliged to go to the UK court (the country she has nothing to do with) just because he decided so.
Actually Wulks, yes, she does. She is very much obliged to respond to a lawsuit against her. She can choose to ignore a summons however that would mean she were I represented and the judge would decide whether to appoint a lawyer on her behalf.
Although it may upset you personally Wulkan that an injured person can sue for compensation in their own jurisdiction, that is the law, and it is easy to collect the damages.
Its up to the Polish legal system to deal with it, and from what I've heard from the legal system in the UK it is, one rule for Poles and another for any foreigner
This is sadly very true and will sooner or later become an issue however regardless of the criminal case involving the woman, the civil case for damages (and the photos suggest he is damaged) can be (and should be if the guy's got half a brain) under English or Scottish (if he lives, works there or has property there) law. Not sue what you mean by UK law - do you mean English law?
am surprised myself.i used bleach without gloves and never had any burns
It was probably some commercial stuff, much stronger than supermarket bleach and if she was handling the hazardous materials as part of her job, she should be expected to know the safety issues. And ignorance of the possible extent of the crime you've committed isn't a defence, just a possible mitigation that a judge is likely to ignore.
