A peer reviewed paper from the ICS? That's like having Tomas de Torqemada discuss the finer points of Judaica.....
Try this out. Physical laws are physical laws. Period. No matter what the ICS says.

Yes the usual ridicule "rational" evolutionists always start resorting to in place of logic. Humphries is an accomplished scientist. If there were any methodological flaws in the analysis evolutionists would be falling all over each other to point them out. What violation of basic scientific principles that you asserted you have always found in creationist arguments can you identify? What's your scientific background by the way?
You don't have to assume the speed of light decayed to conclude a young universe. God could have created the light rays from the stars at the time of creation. There's no basis for asserting that he either couldn't or wouldn't do that. Nor would it be a deception, which is one of the semi-clever arguments people come up with, since nothing requires us to interpret the universe under naturalistic assumptions.
