To my knowledge, there has been no outcome to these lawsuits, as they are still pending. Greer hasn't seen fit to put them on the court docket. The closest to an outcome has been is that arguments were issued a week ago, wherein evidence was entered by Pat verbally into the court record that Terri did not lose her teeth due to nonuse, but rather poor hygiene.
Greer IMHO has no interest in removing Michael as guardian, because naming someone else will mean that all that Michael did/did not do will be looked into. Greer will be exposed for what he has allowed to happen to Terri.
