The majority of opinions of the Supreme Court are so important because they establish legal precedents (A). These legal precedents are then used by lower courts to interpret laws in the future greatly impacting the justice system.

Once India gone, they lost a major source of revenue using which they were using to rule the other colonies. Moreover, India's freedom acted like a catalyst for them to demand freedom. Pretty soon the British had to lose the colonies too, reducing the once mighty kingdom to a humble island.
Probably the most sustained effect was the way India earned freedom - lead by Gandhi and other leaders. It showed the world that a war could be fought spiritually also, without violence. It inspired the leaders elsewhere in the world, most probably Martin Luthar King and Nelson Mandela being the most prominent.
