Don't overlook this statement:
"Friday's decision applies in Massachusetts, and need not be followed by federal judges or by courts in other states."

The question is how other states AG's will view the decision. Foreclosure vary from state to state. Some allow foreclosure non-judicially, some have to go thru a court foreclosure process. Some allow both like Washington. Producing the exhibits for a court foreclosure and what needs to be provided for a non-judicial foreclosure aren't necessarily the same. So, one could say the jury is still out as to what this case really means.
