That says that Russian laws are fair - there's no difference between big companies and regular people. No one is protected. If a bank's client can sign a contract presented by the bank and be responsible to follow the rules in the contract the same should apply the other way around. Bank signed a contract without reading its contents and is required to follow what is written in the contract.
Contract is an agreement between two or more parties. You agree to the terms presented in the contract with your signature. Any law written in a way which protects companies is wrong. There should be no difference between a contract written by John Doe and a contract written by any company.
So what does it say about the rule of law in Russia?
