See that's the thing, it's not that simple. The ruling party which controlled the parliament for a few years is corrupt. The president, who was democratically elected by the majority of the people, used the constitution to suspend said parliament, with the support of the people. It's definitely an unorthodox move but it relates to one of democracy's limitations; what could be done when an elected party represents its own interests and not the people's?
Lots of factors could be at play indeed. I'm certainly not an expert, but if I read correctly, the man has disbanded parliament and ruled by decree since two months, publicly announcing his disregard for the constitution. To me, that does not count as democratic anymore.
