For now, media reports. Even in Dutch, I can't find much that isn't reported in international media as well. From Haaretz:
After a full day of deliberations, from 9:30 A.M. to 4:30 P.M., the judges announced that their next open hearing on the case will be in January 2020. They will deliver their ruling as to whether the Dutch court has jurisdiction to hear a civil suit over the killing, on January 20, 2014, of Muftia Ziada, 70, born in the village of Faluja and a refugee living in the Bureij refugee camp, her sons Jamil, Omar and Yousif, her grandson Shaban and her daughter-in-law Bayan.
The reason why this case might be heard in Dutch courts (in Dutch, from de Volkskrant):
Volgens het beginsel van de universele jurisdictie zijn oorlogsmisdaden vervolgbaar in Nederland als de slachtoffers van die misdaden Nederlands burger zijn en elders geen toegang hebben tot de rechtsgang. Volgens Liesbeth Zegveld, advocate van Ziada, is dat het geval. Palestijnen worden gediscrimineerd in Israël en kunnen formeel wel rechtszaken aanspannen, maar in de praktijk lukt dit steevast niet.
Translated by me:
According to the principle of universal juridiction, war crimes can be prosecuted in the Netherlands if the victims of those crimes are Dutch citizens and have no access to justice elsewhere. According to Liesbeth Zegveld, Ziada's lawyer, that is the case. Palestinians are discriminated against in Israel and while formally they can bring legal proceedings, in practice this regularly does not succeed.
If the case is heard in a Dutch court then the ruling will be published on uitspraken.rechtspraak.nl in Dutch. Translating the page using third-party software will probably give a reasonable translation and it's very likely that it will be reported in English by international media outlets. Given that the subject of the case is an Israeli general turned politician, it's certain that the case will be reported in full by Israeli media.
