The flaw in the system is that the IHSAA generally only investigates eligibility when either the old or new school attempts to block transfer on their portion of the transfer report. That is why a vast majority of transfers are eligible without any pushback or without the IHSAA batting an eye, because both schools signed off. In cases where transfers are blocked by one school, the IHSAA then relies upon the resentful school from which the kid has transferred (or in very rare cases, the school that doesn't want to allow the athlete to transfer in) to build and present their case for ineligibility. It is not that the IHSAA does or does not micromanage the transfer process, the problem is that the entire eligibility investigation system is prejudiced against the athlete from the beginning. If you do any actual research into the IHSAA or case review panel decisions, you tend to see the same schools attempting to block transfers by any decent athlete, across all sports, leaving their school system. Because how dare anyone attempt to leave their school. The irony, like many have already said, is that we all know those same schools are more than willing to accept athletic transfers into their program without self-reporting or attempting to block those incoming transfers' eligibility.
I am not making statements as to the Morans case specifically, because I, like 99% of the people on this message board, do not know all the facts, have not spoken to any of the involved parties, and have not been present to hear the evidence, hearing, or appeal process. From what I do know, I believe the brothers should be eligible to compete and that this was a decision made by the parents in the best interest of their children and the family as a whole.
It is also my opinion that the Morans are also caught in the middle of bad blood that CP feels toward Portage for one reason or another. One specific circumstance that I know of is that CP felt bitter and slighted by Portage sending their second team to the super dual last year, so that Portage's varsity could travel to Michigan for a competition with nationally ranked teams. The CP administration has also made an issue of that situation. Makes one wonder if the Morans weren't high caliber athletes or if they had moved somewhere other than Portage, would the IHSAA even be involved? Also ironic is that while CP is celebrating the college eligibility victory of Jason Tsirtsis, they're also working to steal high school eligibility from the Morans. Just plain sad.
Here's a link to an article from 2010, which addresses the implementation of the case review panel and eligibility rules as the pertain to open enrollment. It's an interesting read. However, a quick overview the case review panel rulings shows that it has been less successful than hoped by Tony Bennett, in that it upholds the decision of the IHSAA a vast majority of the time. I guess that's why there's always the opportunity to appeal to state court as well.
