As does every law that comes down from the Castroists. There is no option for, "back to the drawing board",
When it comes to a vote, there are no options either. So long as one person shows up, its a given. (Much like Maduro's recent convening of a Constitutional Assembly, or ANC. The option was this: "Please vote yes here". Anything else was a spoiled ballot.)
Some noise was made recently about the removal of a gay marriage amendment at the behest of the people, but the Communists will certainly include it, as the Government is top down, not bottom up. What is remarkable is that it was even reported for exclusion. My impression is that they are looking for something to give the world who might otherwise support a leftist (though not necessarily Communist) government.
The information I have seen is that while it does loosen the purse strings (they need cash), it solidifies the Communists hold on power by giving them complete discretion to interpret their new dictates. In other words, THEY will decide what the Constitution says. And in the end, the State still owns everything.
