Tantum devolutum, quantum appellatum
Tantum devolutum, quantum appellatum "transferred so far (only) as challenged" is a Roman law rule that the devolutive of appeals describes. Accordingly, the review by the higher instance ( iudex ad quem ) only includes what has been criticized by the appellant (petitioner), further circumstances or errors in the contested decision need not be taken into account. In this respect, this rule is also a derivation of the procedural and material disposition of the petitioner .
In Germany today, for example, compare, Paragraph 3 and Paragraph 3 ZPO.
