A central, unifying Court like the Federal Court was also ideally suited to bring 50 different jurisdictions into the mainstream on a broad range of issues. Thus, improved racial equality could never have been forced on the old slave states without the heavy arm of the Federal Courts. How does a lone citizen stop a multi-billion dollar corporation from dumping toxic chemicals into the water table? By Making a Federal Case out of it. Unlike in state court, a judgment in Federal Court makes national ripples.
A national and a world economy brings Federal Courts more to center stage, but once a trend is started it is sometimes hard to restrain. Many Federal judges, lawyers and legislators believe that the Federal Government has gone overboard in passing so many criminal and civil laws, that the Federal Courts are overburdened, with the Feds poking into areas that have only very marginal national impact.
If a woman is injured when her Ford Pintos gas tank explodes on impact due to faulty design, she could simply sue Ford and win her damages. Or, she could sue in Federal Court, get the case certified as a class action, thus bringing hundreds of thousands of people into the action, and have the judgment control Ford auto design and marketing on a nationwide basis. That is making a Federal Case out of a single auto accident. Whether this is good or bad depends on your point of view, your politics, and ultimately upon the budget and resources of the Federal Courts.
