Cause and Effects

Cause and Effects CLAT Notes | EduRev

  • Cause is an event which leads to a said effect and this fact is either scientifically proven or logically expected.
  • Technically cause means a sufficient condition i.e. collection of all necessary conditions in the presence of which the effect must take place.
  • But, practically we mean cause to be the immediate and principal reason behind the effect.
  • An immediate cause means a cause that immediately precedes the effect and a principal cause means a cause that was the most important reason behind the effect.
  • Since cause must occur before the effect, we can merely look at the given two events first and by analyzing the tense thus, we can declare which event can’t be a cause.
  • A complete solution strategy is given in the flow-chart.
