Palestine had its own Constitution.
Had its own borders.
Had registration of voters.
Had elections to elect Lawmakers and
Had its own laws on granting Citizenship of Palestine - oh, that included your "relatives" who were issued with Palestinian citizenship.
Go on, show me Israel's Gov and borders in 1922.
Oh, just in case you are wondering whether the Palestinian Gov discriminate against Jews at the time. Here is the Jewish court as written in the Constitution of Palestine. That is correct, their rights were enshrined in the Constitution of Palestine.
Go on, show me the one in Israel's Constitution - oops, they deliberately chose NOT to have one.
Jewish courts as enshrined in the Constitution of Palestine:
53. The Rabbinical Courts of the Jewish Community shall have:–
(i) Exclusive jurisdiction in matters of marriage and divorce, alimony
and confirmation of wills of members of their community other than
foreigners as defined in Article 59.
(ii) Jurisdiction in any other matter of personal status of such
persons, where all the parties to the action consent to their jurisdiction.
(iii) Exclusive jurisdiction over any case as to the constitution or
internal administration of a Wakf or religious endowment constituted before
the Rabbinical Court according to Jewish Law.
Here is the Christian one:
54. The Courts of the several Christian communities shall have:–
(i) Exclusive jurisdiction in matters of marriage and divorce,
alimony, and confirmation of wills of members of their community other
than foreigners as defined in Article 59.
(ii) Jurisdiction in any other matters of personal status of such
persons, where all the parties to the action consent to their jurisdiction.
(iii) Exclusive jurisdiction over any case concerning the constitution
or internal administration of a Wakf or religious endowment constituted
before the Religious Court according to the religious law of the community,
if such exists.
Here is the Muslim one:
52. Moslem Religious Courts shall have exclusive jurisdiction in matters of
personal status of Moslems in accordance with the provisions of the Law of
Procedure of the Moslem Religious Courts of the 25th October, 1333, A.H.,
as amended by any Ordinance or Rules. They shall also have, subject to the
provisions of any Ordinance or of the Order of the 20th December, 1921,
establishing a Supreme Council for Moslem Religious Affairs, or of any
Orders amending the same, exclusive jurisdiction in cases of the
constitution or internal administration of a Wakf constituted for the benefit
of Moslems before a Moslem Religious Court.
There shall be an appeal from the Court of the Qadi to the Moslem Religious
Court of Appeal whose decision shall be final.
And where there are further disputes, it goes to the "Special Tribunal"
55. Where any action of personal status involves persons of different of
religious communities, application may be made by any party to the Chief
Justice, who shall, with the assistance, if he thinks fit, of assessors from the
communities concerned, decide which Court shall have jurisdiction.
Whenever a question arises as to whether or not a case is one of personal
status within the exclusive jurisdiction of a Religious Court, the matter shall
be referred to a Special Tribunal of which the constitution shall be
prescribed by Ordinance.
All of these rights were enshrined in the Constitution of Palestine!!!
Go on, show me the rights of "Minorities" being enshrined in Israel's Constitution!!!
