On the ini­tia­tive of FRFG, mem­bers of par­lia­ment from the CDU, SPD, Green Par­ty and FDP draft­ed a non-par­ty motion to enshrine inter­gen­er­a­tional jus­tice in the Ger­man con­sti­tu­tion.

Jens Spahn (CDU), Peter Friedrich (SPD), Anna Lührmann (Green Par­ty) and Michael Kauch (FDP) had for­mu­lat­ed a joint pro­pos­al in sev­er­al meet­ings, which were accom­pa­nied and mod­er­at­ed by the foun­da­tion. The foun­da­tion also sup­port­ed the con­sul­ta­tions with com­ments by renowned con­sti­tu­tion­al lawyers. The pro­pos­al was pre­sent­ed on 14 July 2006.
The pro­pos­al was to enshrine the state goal of inter­gen­er­a­tional jus­tice in a new Arti­cle 20b of the Basic Law: “The state must observe the prin­ci­ple of sus­tain­abil­i­ty in its actions and pro­tect the inter­ests of future gen­er­a­tions”.
Sec­ond­ly, Arti­cle 109(2) of the Finan­cial Con­sti­tu­tion of the Basic Law was sup­posed to be reword­ed to lim­it the pos­si­bil­i­ties of the gov­ern­ment as well as the Län­der to take on debts in the future and hence cre­at­ing a basic finan­cial law restrict­ing nation­al debt:
“The Fed­er­al Gov­ern­ment and the Län­der must take into account the require­ments of macro­eco­nom­ic bal­ance, the prin­ci­ple of sus­tain­abil­i­ty and the inter­ests of future gen­er­a­tions in their bud­get man­age­ment”.
From FRFG’s point of view, this pro­pos­al to reform the debt order was too timid, but the rep­re­sen­ta­tives could not agree on a more far-reach­ing solu­tion.

The bill was sub­mit­ted to the Bun­destag on 22 Novem­ber 2006 by 104 mem­bers of par­lia­ment from four par­lia­men­tary groups and all age groups. Almost a year lat­er, on 11 Octo­ber 2007, the motion was debat­ed in the ple­nary ses­sion of the Ger­man Bun­destag (LINK min­utes) and was sub­se­quent­ly referred to the Legal Affairs Com­mit­tee for fur­ther delib­er­a­tion and delayed for fur­ther dis­cus­sion, so that no adop­tion took place.
The Par­lia­men­tary Advi­so­ry Coun­cil for Sus­tain­able Devel­op­ment final­ly took the helm and in Octo­ber 2008 con­vened an expert hear­ing at which Dr. Dr. Jörg Trem­mel of the FRFG was also present.

With the res­o­lu­tion of the eco­nom­ic stim­u­lus pack­ages fol­low­ing the bank­ing and finan­cial cri­sis in 2009, the foun­da­tion urged that the mem­bers of par­lia­ment only agree to the eco­nom­ic stim­u­lus pack­age if at the same time a debt brake is intro­duced into the Basic Law that goes beyond the pro­vi­sions of the over-frac­tion­al pro­pos­al dis­cussed so far. In spring 2009, the debt brake was enshrined in the con­sti­tu­tion.
