Legal dispute between the Chapter of St. Servatius and William II of Horn

A legal dispute between the Chapter of St. Servatius and William II van Horn over rights and land ownership in Weert in 1295.

On September 21, 1062, the Roman King Henry IV, in the presence of several imperial dignitaries, confirmed a donation by Otto, Count of Thuringia, and his wife Adela to the Chapter of Saint Servatius in Maastricht, which included land, properties, and rights in Dilsen and Weert (Document No. 1).

This grant was later challenged by William II van Horne (1245–1300), who sought to expand his secular power in Weert and the surrounding area. His violations of the chapter’s rights forced the chapter to sue Wilhelm II before the ecclesiastical court in Liège, which issued a ruling on May 21, 1295 (Document No. 75).

This judgment is notable in that it provides a complete picture of the canon law proceedings as they were customary before the ecclesiastical court in Liège at the end of the 13th century, as well as the legal technicalities that were raised during the proceedings.

Why was the chapter’s lawsuit brought before an ecclesiastical court rather than a secular one? The answer lies in the Church’s universal jurisdiction over all matters in which the interests of the Church are at stake: the so-called causae spirituales and causae spirituales annexae, spiritual matters (pastoral care) and related matters (including the Church’s property rights).

Why was the Roman-canonical procedure applied? The Church operated under Roman law and essentially followed the procedural law of the late Roman Empire, namely the inquisitorial procedure—a rational form of litigation that focused on ascertaining the substantive truth and in which the judge played an active role. In this respect, ecclesiastical jurisprudence differed from secular jurisprudence, which for a long time continued to use the accusatory form of proceedings, in which the judge was passive and the parties settled their dispute through oaths and appeals to divine judgment.

In the document dated May 21, 1295, the bishop—the ecclesiastical judge—of the Diocese of Liège describes, step by step, the course of the proceedings between the chapter and Willem van Horn before delivering his judgment. Essentially, the dispute boils down to the following: The chapter accuses Willem van Horn of violating the chapter’s rights in Weert. The chapter demands that he refrain from doing so in the future and compensate the chapter for the loss of income. The defendant, Willem van Horn, naturally disputes the chapter’s complaint and argues, on the contrary, that he has been entitled to do so from time immemorial.

The chapter therefore urged the magistrate to administer justice, especially since Willem van Horn had already admitted his wrongdoing before a court of law.

Willem van Horn argues in court that the chapter’s complaint is unfounded and that he possesses full jurisdiction in Weert. He cites the open and peaceful possession that he and his predecessors, the Counts of Horn and Altena, have held for more than sixty years. If the chapter and its witnesses dare to claim otherwise, they are committing perjury and giving false testimony. He therefore demands that the official declare the lawsuit unfounded and order the chapter to pay the costs.

Once the basis for the lawsuit (litiscontestatio) had been established, witnesses were heard and cross-examined on both sides. The chapter’s procurator argued that Willem van Horn—contrary to the rules of canon law—had had witnesses examined in Weert and at other locations suspected by the Church, the dean, and the chapter, even though these witnesses could easily have come to Liège to give their testimony before the ecclesiastical judge. The chapter therefore argued that the witness statements in favor of Willem van Horn were null and void. Furthermore, it claimed that coercion and bribery had taken place. Furthermore, Willem van Horn had threatened witnesses who wished to testify in favor of the chapter. Since Willem’s witnesses were individuals of ill repute—frivolous and perjured—including prostitutes, adulterers, and those excommunicated by the Church, the chapter requested that their statements be declared invalid.

As proof of its claim, the chapter presented the original charter of 21 September 1062.

Willem van Horn’s attorney then explained that his client did not dare to travel to Liège in person due to the danger to his life, the unsafe roads, and the political unrest, and asked the prosecutor to provide him with a safe place where he could appear in person to present his case. The magistrate granted this request and designated Maastricht as the location for the continuation of the trial, instructing Master Gilles of Liebertenges to temporarily serve as judge in his stead.

Later, when the official presided over the proceedings once again, Willem van Horn declared that the case in Maastricht had no merit, whereupon he demanded that the chapter’s complaint be dismissed and that the chapter be ordered to pay the costs of the proceedings.

The magistrate then again delegated his authority to a deputy, Master Henneman, the lawyer from Liège in Maastricht, who ruled against Willem van Horn in an interim judgment; whereupon van Horn’s lawyer filed an appeal with the magistrate of Liège, who upheld Master Henneman’s judgment.

Willem van Horn then decided to take the offensive, claiming that the chapter had no authority to take action against him, since the dean and the chapter were allegedly excommunicated to the highest degree. In a preliminary injunction, the official then ruled that Willem van Horn had failed to prove the alleged excommunication and ordered him to pay the costs.

This, in turn, was done against the will of Wilhelm van Horn, who subsequently initiated new proceedings against the chapter until the court of competent jurisdiction ruled on this case as well and determined that the proceedings regarding the chapter’s original claim should continue.

Willem van Horn was not present on the day of the final judgment. Arguing that the divine presence compensated for Willem van Horn’s absence, the official nevertheless ruled in favor of the chapter. He prohibited Willem van Horn from further infringing upon the chapter’s rights in Weert and ordered him to pay damages and court costs.

Willem van Horn was evidently dissatisfied with this ruling, and his successor, Gerard van Horn (1300–1331), brought the case before an ecclesiastical arbitration court in Utrecht once again, which recorded its decision in a new document on December 19, 1306.
