Generally the government's reaction to monopolies is to break up the given companies. (Bell, Standard Oil, etc). However, remember that when you get the government involved with monopolies, generally it’s a safe bet they will remain that way. Look for example at the effect of franchise fees on basically enforcing a cable company’s monopoly within a given city. <br /><br />Anti-Trust law also seems hinge on the consumer, not if the barriers to entry for competitors are extremely high. In which case, you could argue that it should be the US government that brings the case against ULA. Of course, the risk is that they discontinue launches (something that the DoD would NOT like). <br /><br />I think that in this case the judge was right, SpaceX might face high barriers to entry, but in the end they are clearly are faring well in securing contracts in the non-EELV market. I wish all the best to SpaceX, but the NEED a proven track record before they can start to fight Boeing/Lockmart head on, period. They will never win a court case with a paper-rocket. <br />
