What happens if the police illegally seize evidence in violation of the fourth amendment?

In case that the police or any other authority proceeds against the right granted in the Fourth Ammendment, their findings, having been illegally obtained, can not be presented before any court as evidence against any individual, nor a judge could allow to have them as evidence in a trial, because this would ignore the Sixth Ammendment by violating the right to an impartial trial.
