Stark was desobedient, but he had no punishment.
How was Stark disobedient? He was never a member of the SSPX. He was a Jesuit who sought to work with the SSPX. He could be accused of being imprudent for refusing conditional ordination, but he was not disobedient.
And this matter of disobedience comes back to a foundational issue with regard ths the Nine, to Msgr. Lefebvre, to the SSPX, namely, what is ths true canonical nature of the SSPX? Is it a pious union (17 Code, aka association of faithful 83 Code)? Is the SSPX a congregation of common life without vows? In other words, what kind obedience is owed to leadership by members of the SSPX? And this will horrify many here, what kind of obedience do laity seeking the ministry owe to its leadership and priests? I would argue none outside of basic deference owed to anyone in Holy Orders. The SSPX, like all traditionalist priests, have no canonical mission, no jurisdictional authority outside the VERY LIMITED supplied jurisdiction needed to offer Mass and administer sactaments. Their Mass centers are not parishes; their priests are neither pastors nor curates. At best they could be identified as rectors of SSPX houses and chapels.
