Almost all loan agreements can be revoked - European Court of Justice

The only plausible legal option, provided the banks simply accept this, is a revocation without payment of early repayment penalties. However, one should also consider that the wording criticized by the ECJ was probably provided as a template in the contracts by the legislator. To what extent a German court would punish a bank that has adhered to the regulations set by the legislator appears questionable. Furthermore, I consider the claim that one would get the paid interest back to be a bold thesis, since the economic benefit of the borrowed money was utilized. Only if the interest rates had been classified as usurious at the time of contract conclusion would there be a claim for overly paid interest. Everything else is, in my opinion, pure client baiting.

Sorry, but if you revoke, then as if the loan was never used. The revocation takes effect at the time of the conclusion, unlike the termination.

But that you get all interest back across the board and would have to pay nothing for the loan granted is nonsense.
