redress and \u201cmass claims\u201d: a new reality in litigation in Portugal?"},"content":{"rendered":"<p data-start=\"562\" data-end=\"746\">For many years, collective redress was regarded in Portugal as a relatively exceptional mechanism, mainly associated with consumer protection and the safeguarding of diffuse interests.<\/p>\n<p data-start=\"748\" data-end=\"808\">However, the landscape appears to be changing significantly.<\/p>\n<p data-start=\"810\" data-end=\"1116\">The increasing massification of certain disputes, driven by the digitalisation of the economy, the immediate circulation of information, and the growing legal and regulatory awareness, has been creating the conditions for the rise of increasingly sophisticated forms of collective and strategic litigation.<\/p>\n<p data-start=\"1118\" data-end=\"1301\">Today, issues simultaneously affecting thousands of individuals or entities can quickly turn into collective disputes with highly significant legal, financial and reputational impact.<\/p>\n<h2 data-section-id=\"dg7ipx\" data-start=\"1303\" data-end=\"1361\">The expansion of collective litigation into new sectors<\/h2>\n<p data-start=\"1363\" data-end=\"1523\">Although historically associated with consumer matters, collective actions are progressively emerging in much broader and economically sensitive areas, such as:<\/p>\n<ul data-start=\"1525\" data-end=\"1711\">\n<li data-section-id=\"osh9bs\" data-start=\"1525\" data-end=\"1552\">Personal data protection;<\/li>\n<li data-section-id=\"1arl3tx\" data-start=\"1553\" data-end=\"1573\">Digital platforms;<\/li>\n<li data-section-id=\"1r5yy1g\" data-start=\"1574\" data-end=\"1595\">Financial services;<\/li>\n<li data-section-id=\"1vtfyv5\" data-start=\"1596\" data-end=\"1610\">Investments;<\/li>\n<li data-section-id=\"1nek6xm\" data-start=\"1611\" data-end=\"1624\">Healthcare;<\/li>\n<li data-section-id=\"f96sau\" data-start=\"1625\" data-end=\"1639\">Environment;<\/li>\n<li data-section-id=\"1l9qx0m\" data-start=\"1640\" data-end=\"1654\">Competition;<\/li>\n<li data-section-id=\"1kdgauz\" data-start=\"1655\" data-end=\"1669\">Immigration;<\/li>\n<li data-section-id=\"4wm6o9\" data-start=\"1670\" data-end=\"1684\">Nationality;<\/li>\n<li data-section-id=\"7l8fi1\" data-start=\"1685\" data-end=\"1711\">Technological liability.<\/li>\n<\/ul>\n<p data-start=\"1713\" data-end=\"1833\">These are only some examples of areas where there is a growing trend towards the collective aggregation of legal claims.<\/p>\n<p data-start=\"1835\" data-end=\"2048\">In many of these sectors, the combination of high regulatory exposure, a large number of potential claimants and strong media attention creates a particularly favourable context for the emergence of \u201cmass claims\u201d.<\/p>\n<p data-start=\"2050\" data-end=\"2291\">The evolution of European legislation and regulation itself has also contributed to this phenomenon, through the strengthening of collective rights protection mechanisms and the increasing compliance requirements in highly regulated sectors.<\/p>\n<h2 data-section-id=\"xqtyyh\" data-start=\"2293\" data-end=\"2352\">A profound change in the traditional logic of litigation<\/h2>\n<p data-start=\"2354\" data-end=\"2432\">This evolution profoundly changes the way litigation is conceived and managed.<\/p>\n<p data-start=\"2434\" data-end=\"2660\">Situations which, a few years ago, would tend to give rise to multiple dispersed individual disputes are now being structured within a collective framework, often coordinated, with greater judicial and media pressure capacity.<\/p>\n<p data-start=\"2662\" data-end=\"2748\">Furthermore, modern collective litigation is no longer exclusively reactive in nature.<\/p>\n<p data-start=\"2750\" data-end=\"2973\">In many cases, it forms part of broader strategies combining judicial, regulatory, reputational and public communication dimensions, enhanced by the speed of information and the media exposure provided by digital platforms.<\/p>\n<p data-start=\"2975\" data-end=\"3083\">Consequently, the impact of a collective action is no longer limited to the judicial proceedings themselves.<\/p>\n<p data-start=\"3085\" data-end=\"3117\">Its effects may be reflected in:<\/p>\n<ul data-start=\"3119\" data-end=\"3273\">\n<li data-section-id=\"1qy0oxd\" data-start=\"3119\" data-end=\"3146\">Institutional reputation;<\/li>\n<li data-section-id=\"w6mplk\" data-start=\"3147\" data-end=\"3174\">Commercial relationships;<\/li>\n<li data-section-id=\"cif6gm\" data-start=\"3175\" data-end=\"3211\">Investor or client confidence; and<\/li>\n<li data-section-id=\"2qsxqh\" data-start=\"3212\" data-end=\"3273\">Increased regulatory scrutiny by the competent authorities.<\/li>\n<\/ul>\n<h2 data-section-id=\"wwohdl\" data-start=\"3275\" data-end=\"3326\">The increase in reputational and regulatory risk<\/h2>\n<p data-start=\"3328\" data-end=\"3460\">Recent experience demonstrates that the reputational effects of collective litigation often begin long before any judicial decision.<\/p>\n<p data-start=\"3462\" data-end=\"3673\">The mere public disclosure of a potential collective action may generate significant pressure on companies and public entities, influencing market perceptions, media coverage and relationships with stakeholders.<\/p>\n<p data-start=\"3675\" data-end=\"3776\">For this reason, managing this type of risk now requires a multidisciplinary and preventive approach.<\/p>\n<p data-start=\"3778\" data-end=\"3853\">What is at stake is not only the judicial defence of the dispute, but also:<\/p>\n<ul data-start=\"3855\" data-end=\"3959\">\n<li data-section-id=\"5nbdjc\" data-start=\"3855\" data-end=\"3888\">The ability to anticipate risk;<\/li>\n<li data-section-id=\"1u4bmw\" data-start=\"3889\" data-end=\"3911\">Regulatory response;<\/li>\n<li data-section-id=\"4drgoh\" data-start=\"3912\" data-end=\"3932\">Crisis management;<\/li>\n<li data-section-id=\"1f59yab\" data-start=\"3933\" data-end=\"3959\">Reputational protection.<\/li>\n<\/ul>\n<p data-start=\"3961\" data-end=\"4169\">In this context, internal compliance mechanisms, governance, data protection, document management and regulatory monitoring are becoming increasingly important in mitigating exposure to collective litigation.<\/p>\n<h2 data-section-id=\"wu52nw\" data-start=\"4171\" data-end=\"4224\">A growing challenge for companies and institutions<\/h2>\n<p data-start=\"4226\" data-end=\"4316\">The growth of collective redress also raises relevant procedural and strategic challenges.<\/p>\n<p data-start=\"4318\" data-end=\"4482\">Firstly, due to the complexity associated with managing disputes involving a high number of interested parties, cross-cutting impact and potential public relevance.<\/p>\n<p data-start=\"4484\" data-end=\"4682\">But also due to the need for companies and institutions to adapt to a reality in which litigation is increasingly accompanied by media scrutiny, regulatory pressure and heightened reputational risk.<\/p>\n<p data-start=\"4684\" data-end=\"4822\">Everything therefore indicates that collective redress will continue to gain relevance within the Portuguese and European legal landscape.<\/p>\n<p data-start=\"4824\" data-end=\"5033\" data-is-last-node=\"\" data-is-only-node=\"\">And this may become one of the most significant transformations of contemporary litigation in the coming years, not only from a legal perspective, but also in terms of organisations\u2019 strategic risk management.<\/p>\n<p><strong>For
