  • EDPS gui­de­lines pro­vi­de a four-stage check­list for asses­sing the pro­por­tio­na­li­ty of mea­su­res in terms of appro­pria­ten­ess and effectiveness.
  • The gui­de­lines requi­re an assess­ment of the inten­si­ty of the inter­fe­rence, a weig­hing up of fun­da­men­tal rights and, if neces­sa­ry, the intro­duc­tion of pro­tec­ti­ve mea­su­res in the event of disproportionality.

The Euro­pean Data Pro­tec­tion Super­vi­sor (EDPS), the data pro­tec­tion super­vi­so­ry aut­ho­ri­ty over the EU insti­tu­ti­ons, has Gui­de­lines for the pro­por­tio­na­li­ty test (cf. e.g. Reci­tal 4 and Art. 32 GDPR) are published. They con­sist for the most part of a check­list com­pri­sing the fol­lo­wing four steps:

  1. Step 1: assess the importance (‘legi­ti­ma­cy’) of the objec­ti­ve and whe­ther and to what ext­ent the pro­po­sed mea­su­re would meet this objec­ti­ve (effec­ti­ve­ness and efficiency)
  2. Step 2: assess the (scope, ext­ent and inten­si­ty of the) inter­fe­rence in terms of effec­ti­ve impact of the mea­su­re on the fun­da­men­tal rights to pri­va­cy and data protection
  3. Step 3: pro­ce­ed to the fair balan­ce eva­lua­ti­on of the measure
  4. Step 4: ana­ly­sis con­clu­si­ons on the pro­por­tio­na­li­ty of the pro­po­sed mea­su­re. If the con­clu­si­on is ’not pro­por­tio­na­te’, iden­ti­fy and intro­du­ce safe­guards which could make the mea­su­re proportionate.

Like the other EDPS gui­de­lines, the­se gui­de­lines can pro­vi­de gui­dance for the pri­va­te sec­tor as well.
