Article by Roman Huber

I. Einleitung Das Bundesgericht hatte im vorliegenden zur amtlichen Publikation vorgesehenen Urteil eine von der Klägerin und Beschwerdeführerin geltend gemachte Täuschung (E. 3.1– 3.4.3) sowie einen Grundlagenirrtum (E. 3.4.4) im Zusam­menhang mit einer Streitigkeit aus einem Software-Integra­tionsvertrag verneint.

Daneben prüfte es, ob der von der Klägerin und Be­schwerdeführerin nebst Täuschung erklärte Rücktritt vom Projektierungsvertrag sowie von der später abgeschlos­senen Zusatzvereinbarung «unverzüglich» im Sinne von Art. 107 Abs. 2 OR erfolgt ist (E. 4). Ferner äusserte es sich zu der in der Lehre unterschiedlich beantworteten Frage, ob auch bei Anwendung von Art. 108 Ziff. 1 OR eine «unver­zügliche» Erklärung über das weitere Schicksal des Ver­trags hätte erfolgen müssen (E. 4.3). In prozessualer Hin musste das Bundesgericht sich sodann erstmals zu der in der Lehre ebenfalls umstrittenen Frage äussern, ob das angerufene Handelsgericht auch für eine konnexe Wider­klage der Beklagten gegen die nicht im Handelsregister ein­getragene Klägerin und Widerbeklagte zuständig ist (E. 2). Diese Urteilsbesprechung wird sich im Folgenden auf die beiden letztgenannten Themen Leistungsverzicht und sach­liche Zuständigkeit bei Widerklage beschränken.1

II. Sachverhalt und Prozessgeschichte Im Jahr 2011/2012 schrieb die Stadt U. (Klägerin, Wider­beklagte, Beschwerdeführerin, «Kundin») die Gesamter­neuerung ihres Internetauftritts im Rahmen eines Sub­missionsverfahrens öffentlich aus. Die A. AG (Beklagte, Widerklägerin, Beschwerdegegnerin, «Unternehmerin») reichte zusammen mit ihrer Offerte, welche auf der Soft­warelösung B. («Software») beruhte, ein umfangreiches Dossier ein, welches insbesondere das ausgefüllte, auf Selbstdeklaration basierende Formular «Erfüllung Anfor­derungen/Funktionen» enthielt.

In der Folge plausibilisierte die Kundin unter Beizug eines externen Beraters («Berater») die Angaben der Un­ternehmerin. Nachdem die Unternehmerin den Zuschlag erhalten hatte, unterzeichneten die Parteien am 9./10. Au­gust 2012 einen Projektierungs-Vertrag («Vertrag»). Am 31. Oktober/11. November 2013 schlossen die Parteien zu­sätzlich eine «Vereinbarung Entschädigung Zusatzaufwen­dungen» («Zusatzvereinbarung») ab. Aufgrund von Diffe­renzen setzte die Kundin der Unternehmerin mit Schreiben vom 24. Januar und 25. März 2014 Nachfrist an. Die letzte Nachfrist lief am 1. Juli 2014 ab. Die Unternehmerin sand­te der Kundin am 20. August 2014 eine E-Mail, in welcher sie diese anfragte, ob sie für die Fertigstellung personelle Ressourcen für September und Oktober reservieren solle. Die Kundin vertröstete die Unternehmerin betreffend den Entscheid über das weitere Vorgehen auf die Woche des 22. September 2014 und zog ohne Wissen der Unterneh­merin eine Beraterin als Expertin bei. Aufgrund deren Ein­schätzung erklärte die Kundin mit Schreiben vom 22. Sep­tember 2014 schliesslich unter Berufung auf Täuschung, Terminverzug und Kostenüberschreitung den sofortigen Rücktritt vom Vertrag und von der Zusatzvereinbarung.

Mit Klage vom 17. April 2015 beantragte die Kun­din dem Handelsgericht des Kantons Zürich («Handels­gericht»), die Unternehmerin sei zu verpflichten, ihr CHF 513'305.27 zuzüglich Zins zu 5 % zu bezahlen. Sie sicht forderte damit die von ihr an die Unternehmerin geleisteten Zahlungen zurück und machte überdies Schadenersatzan­sprüche geltend. Die Unternehmerin beantragte ihrerseits, die Klage sei abzuweisen, und verlangte widerklageweise, die Kundin sei zur Bezahlung der restlichen vertraglich geschuldeten Pauschalrate von CHF 10'000 nebst Zins zu 5 % sowie zu Schadenersatz in Höhe von CHF 32'205.75 nebst Zins zu 5 % zu verpflichten. Das Handelsgericht wies die Hauptklage mit Urteil vom 9. Februar 2017 ab und verpflichtete die Kundin, der Unternehmerin CHF 10'000 nebst Zins zu 5 % zu bezahlen. Im Mehrbetrag wies es die Widerklage ab.

Mit Beschwerde in Zivilsachen beantragte die Kundin dem Bundesgericht unter anderem, der angefochtene Ent­scheid sei aufzuheben, die Klage sei gutzuheissen und die Widerklage sei abzuweisen. Das Bundesgericht wies die Beschwerde ab.

    Information Collection and Use

    We require site users to register with Mondaq (and its affiliate sites) to view the free information on the site. We also collect information from our users at several different points on the websites: this is so that we can customise the sites according to individual usage, provide 'session-aware' functionality, and ensure that content is acquired and developed appropriately. This gives us an overall picture of our user profiles, which in turn shows to our Editorial Contributors the type of person they are reaching by posting articles on Mondaq (and its affiliate sites) – meaning more free content for registered users.

    We are only able to provide the material on the Mondaq (and its affiliate sites) site free to site visitors because we can pass on information about the pages that users are viewing and the personal information users provide to us (e.g. email addresses) to reputable contributing firms such as law firms who author those pages. We do not sell or rent information to anyone else other than the authors of those pages, who may change from time to time. Should you wish us not to disclose your details to any of these parties, please tick the box above or tick the box marked "Opt out of Registration Information Disclosure" on the Your Profile page. We and our author organisations may only contact you via email or other means if you allow us to do so. Users can opt out of contact when they register on the site, or send an email to unsubscribe@mondaq.com with “no disclosure” in the subject heading

    Mondaq News Alerts

    In order to receive Mondaq News Alerts, users have to complete a separate registration form. This is a personalised service where users choose regions and topics of interest and we send it only to those users who have requested it. Users can stop receiving these Alerts by going to the Mondaq News Alerts page and deselecting all interest areas. In the same way users can amend their personal preferences to add or remove subject areas.

    Cookies

    A cookie is a small text file written to a user’s hard drive that contains an identifying user number. The cookies do not contain any personal information about users. We use the cookie so users do not have to log in every time they use the service and the cookie will automatically expire if you do not visit the Mondaq website (or its affiliate sites) for 12 months. We also use the cookie to personalise a user's experience of the site (for example to show information specific to a user's region). As the Mondaq sites are fully personalised and cookies are essential to its core technology the site will function unpredictably with browsers that do not support cookies - or where cookies are disabled (in these circumstances we advise you to attempt to locate the information you require elsewhere on the web). However if you are concerned about the presence of a Mondaq cookie on your machine you can also choose to expire the cookie immediately (remove it) by selecting the 'Log Off' menu option as the last thing you do when you use the site.

    Some of our business partners may use cookies on our site (for example, advertisers). However, we have no access to or control over these cookies and we are not aware of any at present that do so.

    Log Files

This privacy statement applies solely to information collected by this Web site.

    Surveys & Contests

    From time-to-time our site requests information from users via surveys or contests.

Contact information will be used to notify the winners and award prizes. Survey information will be used for purposes of monitoring or improving the functionality of the site.

    Mail-A-Friend

    If a user elects to use our referral service for informing a friend about our site, we ask them for the friend’s name and email address. Mondaq stores this information and may contact the friend to invite them to register with Mondaq, but they will not be contacted more than once. The friend may contact Mondaq to request the removal of this information from our database.

If you have any questions about the security at our website, you can send an email to webmaster@mondaq.com.

    Correcting/Updating Personal Information

This can usually be done at the “Your Profile” page or by sending an email to EditorialAdvisor@mondaq.com.

    Notification of Changes

    If we decide to change our Terms & Conditions or Privacy Policy, we will post those changes on our site so our users are always aware of what information we collect, how we use it, and under what circumstances, if any, we disclose it. If at any point we decide to use personally identifiable information in a manner different from that stated at the time it was collected, we will notify users by way of an email.
