Article 83 of Ukraine's constitution is very clear, it states. ....
"A coalition of deputy factions comprising a majority of people’s deputies of Ukraine in the constitutional membership of the Verkhovna Rada of Ukraine shall be formed in the Verkhovna Rada of Ukraine on the basis of the results of election and on the basis of the harmonisation of the political platforms. "
Any parliamentary coalition is formed by factions, of which there are currently five, and not by individual deputies.
Because of the difficulty of forming a new coalition and electing a new cabinet led by a PoR premier, the party is proposing the introduction of a new, politically expedient parliamentary 'reglament' or rule - a coalition is to comprise: "a union of deputy fractions, national deputies, into which enter a majority of national deputies from the constitutional body of the Verhkhovna Rada."
The NUNS parliamentary faction has split into smaller groups, and parliament now also includes a number of non aligned deputies who have been kicked out of their factions, so this constitutionally unlawful step may help Viktor Yanukovych and PoR achieve their aim of forming a new majority in parliament and a cabinet led by one of their guys, probably Mykola Azarov. But it will not make the new ruling coalition more durable.
The Verkhovna Rada has been plagued by deputies' political indiscipline for many years - that is why the constitution was changed to its present form in the first place.
Even if a new coalition is not formed in the allotted time frame and fresh pre-term parliamentary elections are called, because 4 or5 or more factions will enter parliament again, sadly, the instability will continue.
