Gonçalves, Condessa and Bizarro turn temporality into an explicit problem of governance. Comparing Portuguese planning reforms from 1999 and 2015, they show that procedural simplification does not automatically generate effectiveness and that expanded participation can create new forms of temporal friction. Their signature distinction separates pathological delay, produced by inefficiency and fragmentation, from productive delay, in which time enables environmental assessment, deliberation or institutional learning. The conceptual operation is to treat planning time as a governable resource rather than a passive cost. Methodologically, the article combines legal and policy analysis with a comparative reading of institutional architectures, producing a framework for temporal calibration across speed, deliberation and foresight. The paper’s importance lies in refusing both the celebration of acceleration and the romanticisation of slowness. Its wider bridge is to democratic governance: temporal design redistributes access, participation and institutional trust because compressed or extended procedures alter who can intervene, when knowledge becomes actionable and how uncertainty is absorbed.
