The Andrade Court was articulating an equity principle regarding the fact that an AG has a conflict of interest with people that they appointed which I believe can be applied directly to the conflict of interest that Obama has with the AG and US Attorney that he appointed.
In both cases, the same principle articulated in Andrade might apply with an qualified interested person as plaintiff/appellant:
The above procedure is cumbersome and could easily operate to deprive a plaintiff with an otherwise legitimate claim of the opportunity to have his case heard. For instance, the Attorney General was responsible for appointing appellees Diegelman and Lauer to their jobs. Requiring appellants to convince the Attorney General to file a quo warranto action on their behalf in this case would effectively bar their access to court.
Regarding Obamas eligibility, so far requiring all appellants to convince the Attorney General (or US Attorney) to file a quo warranto action has effectively been a bar to their access to court.
A procedurally correct quo warranto with a proper “interested person” as plaintiff has not yet been filed in the correct district court in DC, so no one knows how successful such a case might be.
I suspect that Lakin is heading in that direction and also the Chrysler dealers. Let's just see how it plays out.
