The article "The Sovereignty of the People 1918 and 2018" deals with one of the basic questions of constitutional law. What is the People? How the People could affect the heading of the state? This question is also up-to-date, because of Trump "revolution" or Brexit referendum.
In the Czech Republic the 2018 president election seems to be also significant moment. Conclusion of the Article is based on deduction, that it is hazardous to understand "the People" only as an abstract body with no real will and power.
Nevertheless, the opposite extreme is also potentially harmful. The People could not be seen as the sum of citizens or even only registered voters in the state.
