If it was, we would have no way of knowing.
The entire basis of relativistic physics is that the speed of light is a constant, no matter your frame of reference. So, since every frame of reference is relative to the speed of light, we could not possibly tell whether or not it was changing.
There are some who theorize that if the expansion of the universe is slowing, then the speed of light must be slowing. Again, however, what is it slowing relative to? We have no point of reference outside our universe, so the point is moot.

The Speed of light is the speed of light. It's always going to be the same. How could it change? If something is measured as going as fast "as the speed of light" how can one tell if the speed of light itself is slowing down?

The speed of light will always "C" in empty space.
You can slow it down in mediums of higher optical density.
It can never be stopped.
If computer scientists eventually harness a single photon as a single bit it will always be in a state of continued acceleration.

You're probably thinking of the theory of "tired light" which was a weak attempt by the Big Bang theory haters to discount the theory by stating that galactic redshift was caused by photons losing energy over massive distances (rather than the truth, which was that the Universe is expanding.) I think Fritz Zwicky was the 1st to propose this theory.
The bottom line is that its wrong.

Speed of light is constant 3x10^8 cm/sec

Hi. Not measurably with todays technology.

No convincing case has been made for this, although there has been some theorizing about it.

where you got this information? only then i can answer... C is always constant if not then relativity is not true..
