The Russian joint-stock company for a long time

For a long time, a Russian joint-stock company bought products from a Latvian farm and, under a long-term supply contract, transferred monthly amounts to its account to pay for it. At the beginning of 1995, the details of the supplier’s bank account changed, which the joint-stock company was not notified about and paid for the next batch of goods according to the old details. As a result, the money went to the account of one of the Riga companies, which in Russia had its own branch. The Russian joint-stock company turned to the company with a request to return the amount illegally received, but it did not respond to the request and did not return the money.
