God's election is just because it stems from His unchanging nature of righteousness and justice, as affirmed in Romans 9.
The righteousness of God is a core attribute that cannot be separated from His actions, including the way He elects individuals for salvation. As stated in Romans 9:14-16, any suggestion of unrighteousness in God's choosing is blasphemous since God operates out of His inherent righteousness. Throughout Scripture, God's dealings with humanity show that He is always just, and His mercy towards the elect does not violate justice. Instead, it reveals His grace and highlights the seriousness of sin that all humans deserve punishment for. In executing His sovereign plan, God’s righteousness is showcased as He has the prerogative to have mercy on whom He will, thereby fulfilling His character without contradiction.
