'discrimination in the selection of the grand jury remains a valid ground for setting aside a criminal conviction*' rose v mitchell (1973 or 1980 the other which has developed many interesting holdings is Hobby v US)
most recent has been 2015 with TN telling the federal court they will continue doing rule of man grand juries as they have done since around 1912, greatly deviating from the federal model.
I'll pull up my notes on habeas dismissal of indictments with prejudice.
'Accordingly, we reverse the judgment of the Court of Criminal Appeals to the extent that it holds that challenges to an indictment can never be addressed in a habeas corpus proceeding.' dykes v compton 1998
from rose to dykes, it is not a large leap to challenging an indictment and dismissing the charge with prejudice with the DA losing standing to present again
I'll be back with some more on this subject
*even the grand jury foreman and even if he didn't vote..... therefore easy step to include alternates
