Generate text that refutes this claim: Prosecutions of politicians are often motivated by partisan concerns.  As noted above, the political life is steeped in difficult decisions, and some of these are bound to result in choices that are at least potentially illegal. The ability to prosecute politicians incentivizes political opponents to search out past actions by said politicians so as to immobilize them politically. Such prosecutions are therefore not motivated by concern for justice, nor are they conducive to a well-functioning, multipartisan political system wherein representatives seek to work together to achieve their political ends. In the most extreme cases, powerful politicians use prosecutions to immobilize their political opponents.

Motivation does not matter. Almost every time someone presses criminal charges, it is for their own personal concerns (such as wanting retribution), rather than concern for the public good; that does not change the fact that if charges are laid, it is because the prosecuting authority has decided that, regardless of why the crime has come to their attention, the interest of society at large requires that the individual be prosecuted. If political motivations are what is needed for politicians to be held accountable, so be it. Even if this is a problem, it can be mitigated with sufficient oversight from an independent prosecuting authority.
