I’m no family lawyer. But litigators everywhere should be aware of what can happen in family courts, which wield huge power over the lives of individuals. These courts have an odd way with expert evidence, which raises basic questions about the rights of the defence.

Consider this scenario, based on a true story. You return home with new baby, the midwife visits him at 11 days and thinks he’s fine, but later he becomes floppy. You go to casualty. Your baby has seizures, which are investigated. Nothing concrete can be detected and finally he goes home.
