The Living Church has published this news report: Formal Charges Lodged Against Connecticut Bishop which explains more about the process.
The Connecticut Six have now taken formal action under Episcopal canon law against their diocesan bishop, Andrew Smith, by filing charges against him in accordance with TITLE IV, CANON 3 (PDF file) of the Episcopal Church.
The full text of these charges can be found in a 1.2 Mb 22-page PDF file, available here.
A press release from the American Anglican Council is here.
The charges have been filed by a total of 19 persons, all of whom are it seems either clergy at, or communicants at, the six parishes who are already in dispute. Some of the names are hard to read from the PDF, but I expect a list will be published somewhere shortly.
The charges accuse the bishop of “undermining the structure of the Episcopal Church and denying canonical due process for the so-called ‘Connecticut Six’ clergy” and include “violating the Episcopal Church’s Constitution, national canons, diocesan canons, and the laws of the state of Connecticut”.
I will add further links here as other reports are published. But what happens next, it appears, is this:
Sec. 26. Any Charge against a Bishop shall be filed with the Presiding Bishop who shall promptly communicate the same to the Respondent. The Presiding Bishop shall forward the Charge to the Review Committee at such time as the Presiding Bishop shall determine or when requested in writing by the Complainant or Respondent after 90 days of receipt of the charge by the Presiding Bishop…
…Sec. 40. Within sixty days after receiving a Charge, the Review Committee shall convene to consider the Charge. If after such consideration the Review Committee determines that an Offense may have occurred if the facts alleged be true, the Review Committee shall prepare a written general statement of the Charge and the facts alleged to support the Charge and transmit the same to the Church Attorney.
What is not at all clear is how this action will affect the earlier appeal made to the international Anglican Panel of Reference.
