I'm in an alliance with two other empires, and I want to declare war on another empire which currently has one planet.

The target empire only has one planet, which I want to take for myself but my allies keep voting no when I propose war. Is there a way I can declare war without needing the apporval of my allies and without leaving the alliance?

No, an alliance goes to war entirely or not at all. You could demand vassalization from a one-planet empire though.
