A reader has forwarded the information that the 4th Circuit has upheld the guidelines in their entirety, within hours of hearing argument.
I wait to see how the judges justify this conclusion (and wish I could say I am shocked). Apparently there are also dissents.
The appellate court has also "recommended" that trial courts issue dual sentences.
More information as I get it . . .
[addendum] Sentencing Law & Policy has the actual order here.
