The 'Bonner Kommentar' is the oldest and most extensive commentary on the German Basic Law, published as a loose-leaf collection since 1950 and now filling 25 binders.
Notes on verification
Core claim corroborated by Wikipedia, multiple library catalogs, and publisher listings. Minor discrepancy in binder count across sources (17 vs 25) attributed to edition growth over time; current sources consistently confirm 25 binders.
