Let's do an example. The Supreme Court knocked down anti-sodomy laws. Congress can, by vote of the majority, put them back. How about Roe v. Wade? Desegregation?
Now, those are cases where local laws were overturned- but there have been federal laws struck down by the USSC too. If this bill were to pass, which I highly doubt it will, the Supreme Court is at the whim of congress. Essentially, congress gets the final say on whether or not something is constitutional.
As a rule, you don't let the people making the laws have the final review on whether or not those laws are allowed by the meta-ruleset that describes the appopriate functions.
::facepalm:: I hope someone realizes that Rep. Ron Lewis was scraped out of the filter of the gene pool. I mean, you can see that he's not very bright. Actually... he kinda looks like our landlord.
