Papal election:

As a critical part of the selection and installation and execution of the office and powers of the pontiff is the 'Recognition by the Members of the Church [including the less formal members of the Mystical Body of Christ] of the Essential Legitimacy of that Selection Process', the vote to select a successor to St. Peter is to be:
A.  OPEN, and not done in secret, and with 'open' meaning with access by the public and the mass media to the formal       proceedings, at least as much as possible while still implementing responsible concern for orderliness and security       [see Addendum A -- required model, but adjustable];
B.  EXPANDED, and not limited to only formal members of the Catholic Church [see Addendum B -- required                model, but adjustable];
C.  INCLUDED, to be the same general procedure and voter proportions in Ecumenical Council operation & 
D.  DECISIONS, by vote of sixty percent of all possible votes.

openness of voting to mean live broadcasts via radio & television & www by at least ten randomly selected reporters/witnesses who will operate with only two assistants each and from enclosed booths which will be distant from electors/voters but visible of & by them, and with audio pick-up of the electors'/voters' assembly area, and of whoever addresses the assembly;
'randomly selected' means by Pontifical Council for Social Communications via public lottery type dart board elimination procedure involving at least one hundred of the most respected world news outlets as decided by the self-same Pontifical Council for Social Communications.

the proportion of voters in Papal Elections and in the Ecumenical Councils is to be:
a.  Catholic                                                                                               60%
b.  Orthodox                                                                                             12%
c.  other Christian, traditional since before 1899                                         11%
d.  other Christian, non-traditional since 1899                                              3%
e.  non-Christian religions                                                                           11%
f.  ethical philosophy groups                                                                        3%

where selection of participating group/church is not clearcut, then decision by Vatican's Tribunal of the Roman Rota;

each group/church is assigned member/voter representation in proportion to member size and duration of existance [size = 66.66%; duration = 33.33%],
and with  membership based on those who attend some formal religious-service/philosophy-discussion at least twice per year -- appeal for final decision on dispute on this issue is to be to Vatican's Pontifical Council for Dialogue among Religions;

each group/church is responsible for own selection of representatives [of equal standing regardless of age, sex, race, intelligence, legal status, etc.],
but if not done in timely manner due to internal dispute/disorder or any other reason,
then selection for them of the unassigned representatives is by Mother Superior of Sisters of the Presentation of the Blessed Virgin Mary.
