Why did Gandhiji feel that taking the Champaran case to the court was useless ?

Cz he thought courtes are not good enough to justify the real pain of the peasants in chqmparan

This was because the courts did a little good to the peasants and they were so grieved and pain striken that the law couts could not take sufficient legal actions.
 

Gandhiji felt it was useless to take the Champaran case to court as it was a British court and the judge was a British person so they will never get anything in their favour and also the eminent lawyers were charging a huge amount which the peasants could never afford.

why is grandeur associated with the mighty dead
 

because he thought that court could not take sufficient legal action.He also felt that as the peasant were fire stricken the real relief would make them fearless. 

When Gandhiji got to know about the plight of the peasant groups in Champaran from his discussion with the lawyers, he came to the conclusion that the poor peasants were so crushed and fear-stricken that law courts were useless in their case. Going to courts overburdened the sharecroppers with heavy litigation expenses. What really needed to be done was to make them free from fear.

According to gandhiji where peasants were so crushed and fear stricken law court were unless / lawyers were collecting big fees from peasants / little hope of getting justice as the case was against the british landlords
