Is achieved by informal deliberations

Explanation:

In a civil case the decision of a jury is achieved by informal deliberations. It does not have to be a unanimous decision. The judge has the power to instruct the jurors on the number of jurors needed to come to a conclusion or reach a verdict. Upon informal deliberations and examining evidence, if the jurors come to a unanimous decision, the verdict is signed by the foreperson. If on the other hand, the verdict of the jurors is not unanimous, only the jurors who agrees with the verdict signs.

the fourth amendment protects:

"the right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."  

so this would mean the denial to search and seizure without warrant or permission.
