The c-axis resistivity measurements in 
from Hussey et al. for magnetic field
orientations along the c-axis
as well as within the ab-plane are analyzed and interpreted
using the scaling theory for static and dynamic classical critical phenomena. We
identify a superconductor to normal conductor transition for both field
orientations as well as a normal conductor to insulator transition at a
critical field 
with dynamical critical exponent z=1, leading
to a multicritical point where superconducting, normal conducting and insulating
phases coexist.
