Parent poster was considering ways on how to limit abuse of a certain political power, and I thought they may be interested on how other countries handle it. (Not though that I am not sure our indian approach is necessarily right - the Supreme Court of India is considering the Presidential powers of pardon only as a remedy to some judicial injustice / miscarriage. But sometimes there can be a political reason too, to pardon somebody. For example, someone cited the Lincoln example of pardoning the confederates. Legally, that may not be sound (ignoring crimes committed by them) but politically such things may be necessary to heal a society and create politically stability. And in such cases, the judiciary is not the right institution to make a judgement call on whether a political pardon was right or not.)
