Assumption: "(Hague Convention) If the foreign court's proceedings were unfair to me, the English court will look into that when deciding whether to send my child back."

Court Reality

The English court will not investigate how fairly the child's home country conducted its own proceedings. Complaints about judicial conduct, translation, or process belong in that country's own courts and appeal system, not in a Hague Convention application. English courts give due respect (comity) to the foreign court's ongoing welfare decisions rather than re-examining how they were reached.
