Learn Finnish: Me pidetään tota päätöstä epäreiluna.

This sentence uses the exact structure taught in this lesson: pitää + partitive + essive. When you express that you consider something to be a certain way, the adjective describing it takes the essive case (epäreiluna).

Why are tota and päätöstä in the partitive case?

In this specific pitää structure, the thing you are judging must be in the partitive case. tota päätöstä is the partitive form of tuo päätös (that decision).

I thought pitää meant 'to like' or 'to have to'. How does it mean 'consider' here?

The meaning of pitää changes depending on the grammar around it. You already know that pitää + elative case (-sta/-stä) means 'to like', and pitää + infinitive verb means 'to have to'. But when combined with a partitive object and an essive adjective, it translates to 'to consider' or 'to find something to be'.

Pidetään is a passive verb form. Why is it translated as the active 'we consider'?

In spoken Finnish, the passive form is almost always used for the first-person plural ('we') instead of the standard dictionary form. Rather than the formal written me pidämme, everyday speech uses me pidetään. The word tota is also a spoken-language version of tuota, keeping the whole sentence casually consistent.
