It is shown that the lack of objective existence of the results of quantum measurements of the state of collapse of the state vector of a remote localized system cannot be proved by an experiment using the fact of violation of Bell's inequality of the Clauser—Horne—Shimony—Holt type. The arguments of a general nature and a specific calculation example confirming this conclusion are also given.
