I vow on my honor....
There is nothing in the Czech Constitution to prevent the president from bringing down his own prime minister. The president can undermine him, plot against him, veto his laws, block his nominations, leak his personal letters or systematically belittle him. The Constitution merely requires that the president- elect vow to be true to his country, to uphold its Constitution and its laws, and to act in the interest of the people. The Constitution doesn't require the president to keep this vow once he is inaugurated. He is not legally responsible for his actions, cannot be prosecuted for legal violations and is immune for life for any criminal act committed while in office. The only exception is high treason. The only other thing limiting the actions of the president is his honor. A president striving to bring down his own prime minister must therefore be acting in the interest of the people ... or have no honor.
