This may well be irrelevant but many years ago I worked in a dept dealing with payments. One client had been overpaid and, after about 18 months the parent company found out(or decided to get it back) and pursued the client for the money. The client's solicitor used words to the effect of 'my client claims estoppel' and the claim was dropped. At the time I understood that it was as the debt had not been chased for a long time. The dictionary meaning of estoppel is:(posted 8548 days ago)'Law - the principle which precludes a person from asserting something contrary to what is implied by a previous action or statement of that person or by a previous pertinent judicial determination.'
The law dictionary definition is as you would expect, totally meaningless.
Has anyone any thoughts on this - preferably in plain english - it is probably of no use but there's always a chance.
