Your analogy to Elie is simplified to the extent that when American Native Indians presented their claims, the federal government would always intervene through federal tribunals.Especially when Indian land claims filed, had authorative proof of agreements were broken by the powers that be in their day with a particular tribe. Decisions by the tribunal took into consideration what the impacts would have territorially, financially, and new land assessments to be brokered. It is unfortunately a rule of law that requires those claimants to show proof to the occupiers. Ever been confronted with a claim on your newly purchased home after being granted title, a distant relative of the previous owner has laid claim to your property as a defective title search snafu? Not fun at all when you trusted all involved towards the purchase.
