There are so many possibilities, that it is hard to say whether one or the 
other has ever occurred. In any case, I have never heard of any verified 
observations that the inner or outer layers revolve at different rates. 

One possibility, however, is that, since the core of the earth is liquid at 
varying temperatures, densities and viscosity's, its rotation at different 
depths could lag behind the rotation of the outer solid shell due to frictional 
and turbulent forces. Whether or not this rotational disparity could result in 
pole shift is anyone's guess.  

Another possibility is that the different viscosity's and densities, coupled 
with such lag, along with the precessional wobble, could cause the core to 
change the Earth's center of gravity over long periods of time. If this isso, 
then it could cause an imbalance that might change the precession of the 
current poles and thus an adjustment that resets the Earth's rotation on another 
axis. Of course, there are other possibilities, such as close cometary passes, 
near collision with an extraterrestrial body, planetoid, asteroid, etc., that 
could cause a pole shift.  

However, the only evidence we have that such pole shifts may have occurred in 
the past (other than shifts of magnetic polarity) is the vast belts of 
earthquakes and volcanoes at different great circles around the Earth that could 
represent previous shifting of the Earths equator and the consequent settling, 
rising, and cracking of its surface, as the new equator swells and expands and 
the old equator shrinks and contracts.  

The only reason we might accept such a shift as up to 30 degrees would be if 
we found it consistent with the radial angle of separation between the various 
earthquake and volcanic belts that night indicate such pole shifts occurring 
in the past.  

But, at the moment -- since such belts could be attributed to plate tectonic 
movements and collisions (although, this theory is still controversial** and 
may or may not be entirely true) -- all this is no more than speculation, and 
has no valid scientific basis of credibility to justify or verify it.  

That's the best I can do. Hope it helps,

Lenny
