Repairing Nečas's natural disasters

MP Jeroným Tejc of ČSSD said that after the lower house has been dissolved, his party must use its majority in the Senate to revoke the planned tax exemption for dividends. The Constitution allows the Senate to pass only "essential" legal measures when Parliament is operating in a unicameral mode. Tejc's new spiritual leader within ČSSD, Michal Hašek, told ČT that a dividend tax is just such an urgent measure when the state budget is desperate for every crown. However, Chief Justice Pavel Rychetský of the Constitutional Court told Právo that "essential" could relate to something like a natural disaster. If his court is called upon to decide on the dividend tax, how will Rychetský vote? Is a 0% dividend tax the equivalent of a natural disaster? Rychetský almost always sides with Miloš Zeman, and Zeman referred to the Nečas/Kalousek cabinet as catastrophic. So it's not so far-fetched to suspect that Rychetský's court, if asked, would uphold any Senate measure that serves to reverse the "catastrophe" inflicted on Czechs by Nečas and Kalousek.
