The RPF, GPV, and SGP differed in their attitudes towards electoral cooperation. Since its founding in 1975, the RPF aimed for "cooperation with other [...] political groups that, like the RPF, advocate policies based on God's Word." The SGP was traditionally committed to independence but collaborated locally with ARP and CHU in the 1950s until they merged into the CDA. The GPV had long-standing principled objections to list combinations but became increasingly open to them from the 1980s. For the 1984 European Parliament elections, the GPV – after much internal controversy – agreed to a list combination for the first time.<ref name="HippeVoerman">{{Cite web|url=https://pure.rug.nl/ws/portalfiles/portal/15931185/2010_Gerrit_Voerman_Joop_Hippe_Reformatorisch_Staatkundig_Verbond_Van_de_Marge_naar_de_Macht.pdf|title=Reformatorisch Staatkundig Verbond?

In the following years, the GPV began to take a more flexible stance towards cooperation. In 1994, objections arose from the SGP after the RPF proposed a female candidate for the joint list for the European Parliament elections. Ultimately, the candidate withdrew, allowing for joint participation. The SGP board then declared that participation in a joint list with a woman remained unacceptable in principle. Only if a joint seat could yield an extra seat or a better position in the composition of the executive board were negotiations possible, but women were still not allowed in an electable position. The RPF and GPV responded by setting rules ensuring they would not be forced to exclude women from joint lists.<ref name="HippeVoerman" />
