Is obtaining a right by any means considered unlawful, especially if there is no other way to obtain it?

The questioner's statement, "Obtaining a right by any means is unlawful," is incorrect, as some means of attaining a right are lawful, and others are unlawful. To understand what the questioner means, he must clarify the right he is claiming and the means he intends to use, so that a ruling can be issued concerning them.
