If you already downloaded my paper, get the new
version, since there was an error in the old one.

For some ideal quantum mechanical measurements,
conservation laws would be effectively violated
systematically at a macroscopic level, as shown for
the example of a Stern-Gerlach device. Due to
macroscopic decoherence, that could not occur. The
contradiction is resolved by considering the effect of
small error terms that must be present due to the
uncertainty of properties of the measuring device.
