You are saying that equal cases must necessarily be treated equally. But how do we know that cases are ever equal? There are always similarities and differences between cases. Which ones count? Can we ever identify the relevant features of the cases?

What if cases are so radically contextualized that we can never identify the relevant characteristics in such a way as to formulate general principles?

What if the search for general principles is just a mistake? A will-o-the-wisp we are chasing because we think that there 'must' be law-like principles?
