Implied Warranty

It wasn't written on the box when you bought those turbo charged, um, self-massaging devices...that the tip end wouldn't spark like a firecracker on July 4. It was implied that the product wouuld at least vibrate and not cause a fire or burn or whatever.

That was an implied warranty of gentle goodness.

Not everything must be explicitly written down by lawyers for there to exist a kind of implied covenant or trust. Human beings don't have to be explicitly told, "Now, you people...you shall not murder each other." Okay, well...maybe that one was, in fact, written down. But not by a human, anyway.

Some warranties to product quality, behavior, and property condition (like, no nuclear waste on that 40-acre ranch you bought) are just implied warranties, so they hold teeth in court when the wronged purchaser sues. And wins.
